DNF Configuration Reference
Description
DNF by default uses the global configuration file at /etc/dnf/dnf.conf
and
all *.repo files found under /etc/yum.repos.d
. The latter is typically used
for repository configuration and takes precedence over global configuration.
The configuration file has INI format consisting of section declaration and
name=value
options below each on separate line. There are two types of sections
in the configuration files: main and repository. Main section defines all global
configuration options and should be only one.
The repository sections define the configuration for each (remote or local)
repository. The section name of the repository in brackets serve as repo ID reference
and should be unique across configuration files. The allowed characters of repo ID
string are lower and upper case alphabetic letters, digits, -
, _
, .
and :
. The minimal repository configuration file should aside from repo ID
consists of baseurl, metalink
or mirrorlist option definition.
Distribution-Specific Configuration
Configuration options, namely best and skip_if_unavailable, can be set in the DNF configuration file by your distribution to override the DNF defaults.
[main] Options
allow_vendor_change
-
If disabled dnf will stick to vendor when upgrading or downgrading rpms. Default is
True
Warning
This option is currently not supported for downgrade and distro-sync commands
arch
-
The architecture used for installing packages. By default this is auto-detected. Often used together with ignorearch option.
assumeno
-
If enabled dnf will assume
No
where it would normally prompt for confirmation from user input. Default isFalse
.
assumeyes
-
If enabled dnf will assume
Yes
where it would normally prompt for confirmation from user input (see also defaultyes). Default isFalse
.
autocheck_running_kernel
-
Automatic check whether there is installed newer kernel module with security update than currently running kernel. Default is
True
.
basearch
-
The base architecture used for installing packages. By default this is auto-detected.
best
-
True
instructs the solver to either use a package with the highest available version or fail. OnFalse
, do not fail if the latest version cannot be installed and go with the lower version. The default isFalse
. Note this option in particular can be set in your configuration file by your distribution. Also note that the use of the highest available version is only guaranteed for the packages directly requested and not for their dependencies.
cachedir
-
Path to a directory used by various DNF subsystems for storing cache data. Has a reasonable root-writable default depending on the distribution. DNF needs to be able to create files and directories at this location.
cacheonly
-
If set to
True
DNF will run entirely from system cache, will not update the cache and will use it even in case it is expired. Default isFalse
.API Notes: Must be set before repository objects are created. Plugins must set this in the pre_config hook. Later changes are ignored.
check_config_file_age
-
Specifies whether dnf should automatically expire metadata of repos, which are older than their corresponding configuration file (usually the dnf.conf file and the foo.repo file). Default is
True
(perform the check). Expire of metadata is also affected by metadata age. See also metadata_expire.
clean_requirements_on_remove
-
Remove dependencies that are no longer used during
dnf remove
. A package only qualifies for removal viaclean_requirements_on_remove
if it was installed through DNF but not on explicit user request, i.e. it was pulled in as a dependency. The default is True. (installonlypkgs are never automatically removed.)
config_file_path
-
Path to the default main configuration file. Default is
/etc/dnf/dnf.conf
.
debuglevel
-
Debug messages output level, in the range 0 to 10. The higher the number the more debug output is put to stdout. Default is 2.
debug_solver
-
Controls whether the libsolv debug files should be created when solving the transaction. The debug files are created in the ./debugdata directory. Default is
False
.
defaultyes
-
If enabled the default answer to user confirmation prompts will be
Yes
. Not to be confused with assumeyes which will not prompt at all. Default isFalse
.
diskspacecheck
-
Controls whether rpm should check available disk space during the transaction. Default is
True
.
errorlevel
-
Error messages output level, in the range 0 to 10. The higher the number the more error output is put to stderr. Default is 3. This is deprecated in DNF and overwritten by --verbose commandline option.
exclude_from_weak
-
Prevent installing packages as weak dependencies (recommends or supplements). The packages can be specified by a name or a glob and separated by a comma. Defaults to
[]
.
exclude_from_weak_autodetect
-
If enabled, dnf will autodetect unmet weak dependencies (recommends or supplements) of packages installed on the system. Providers of these weak dependencies will not be installed by dnf as weak dependencies any more (they will still be installed if pulled in as a regular dependency). Defaults to
true
.
exit_on_lock
-
Should the dnf client exit immediately when something else has the lock. Default is
False
.
gpgkey_dns_verification
-
Should the dnf attempt to automatically verify GPG verification keys using the DNS system. This option requires the unbound python module (python3-unbound) to be installed on the client system. This system has two main features. The first one is to check if any of the already installed keys have been revoked. Automatic removal of the key is not yet available, so it is up to the user, to remove revoked keys from the system. The second feature is automatic verification of new keys when a repository is added to the system. In interactive mode, the result is written to the output as a suggestion to the user. In non-interactive mode (i.e. when -y is used), this system will automatically accept keys that are available in the DNS and are correctly signed using DNSSEC. It will also accept keys that do not exist in the DNS system and their NON-existence is cryptographically proven using DNSSEC. This is mainly to preserve backward compatibility. Default is
False
.
group_package_types
-
List of the following: optional, default, mandatory. Tells dnf which type of packages in groups will be installed when ‘groupinstall’ is called. Default is:
default, mandatory
.
ignorearch
-
If set to
True
, RPM will allow attempts to install packages incompatible with the CPU’s architecture. Defaults toFalse
. Often used together with arch option.
installonlypkgs
-
List of provide names of packages that should only ever be installed, never upgraded. Kernels in particular fall into this category. These packages are never removed by
dnf autoremove
even if they were installed as dependencies (see clean_requirements_on_remove for auto removal details). This option append the list values to the default installonlypkgs list used by DNF. The number of kept package versions is regulated by installonly_limit.
installonly_limit
-
Number of installonly packages allowed to be installed concurrently. Defaults to 3. The minimal number of installonly packages is 2. Value 0 means unlimited number of installonly packages. Value 1 is explicitly not allowed since it complicates kernel upgrades due to protection of the running kernel from removal.
installroot
-
The root of the filesystem for all packaging operations. It requires an absolute path. See also –installroot commandline option.
install_weak_deps
-
When this option is set to True and a new package is about to be installed, all packages linked by weak dependency relation (Recommends or Supplements flags) with this package will be pulled into the transaction. Default is
True
.
keepcache
-
Keeps downloaded packages in the cache when set to True. Even if it is set to False and packages have not been installed they will still persist until next successful transaction. The default is
False
.
logdir
-
Directory where the log files will be stored. Default is
/var/log
.
logfilelevel
-
Log file messages output level, in the range 0 to 10. The higher the number the more debug output is put to logs. Default is 9.
This option controls dnf.log, dnf.librepo.log and hawkey.log. Although dnf.librepo.log and hawkey.log are affected only by setting the logfilelevel to 10.
log_compress
-
When set to
True
, log files are compressed when they are rotated. Default isFalse
.
log_rotate
-
Log files are rotated
log_rotate
times before being removed. Iflog_rotate
is0
, the rotation is not performed. Default is4
.
log_size
storage size
Log files are rotated when they grow bigger than log_size bytes. If log_size is 0, the rotation is not performed. The default is 1 MB. Valid units are ‘k’, ‘M’, ‘G’.
The size applies for individual log files, not the sum of all log files. See also log_rotate.
metadata_timer_sync
time in seconds
The minimal period between two consecutive
makecache timer
runs. The command will stop immediately if it’s less than this time period since its last run. Does not affect simplemakecache
run. Use0
to completely disable automatic metadata synchronizing. The default corresponds to three hours. The value is rounded to the next commenced hour.
module_obsoletes
-
This option controls whether dnf should apply modular obsoletes when possible. Default is
False
.
module_platform_id
-
Set this to $name:$stream to override PLATFORM_ID detected from
/etc/os-release
. It is necessary to perform a system upgrade and switch to a new platform.
module_stream_switch
-
This option controls whether it’s possible to switch enabled streams of a module. Default is
False
.
multilib_policy
-
Controls how multilib packages are treated during install operations. Can either be
"best"
(the default) for the depsolver to prefer packages which best match the system’s architecture, or"all"
to install packages for all available architectures.
obsoletes
-
This option only has affect during an install/update. It enables dnf’s obsoletes processing logic, which means it makes dnf check whether any dependencies of given package are no longer required and removes them. Useful when doing distribution level upgrades. Default is ‘true’.
Command-line option: –obsoletes
optional_metadata_types
-
List of metadata types to be loaded in addition to
primary
,modules
,comps
,updateinfo
andpresto
, which are loaded always.Note that the list can be extended by individual commands to explicitly request loading specific metadata type.
Currently only
filelists
value is supported. Default is an empty list.
persistdir
-
Directory where DNF stores its persistent data between runs. Default is
"/var/lib/dnf"
.
pluginconfpath
-
List of directories that are searched for plugin configurations to load. All configuration files found in these directories, that are named same as a plugin, are parsed. The default path is
/etc/dnf/plugins
.
pluginpath
-
List of directories that are searched for plugins to load. Plugins found in any of the directories in this configuration option are used. The default contains a Python version-specific path.
plugins
-
Controls whether the plugins are enabled. Default is
True
.
protected_packages
-
List of packages that DNF should never completely remove. They are protected via Obsoletes as well as user/plugin removals.
The default is:
dnf
,glob:/etc/yum/protected.d/*.conf
andglob:/etc/dnf/protected.d/*.conf
. So any packages which should be protected can do so by including a file in/etc/dnf/protected.d
with their package name in it.DNF will protect also the package corresponding to the running version of the kernel. See also protect_running_kernel option.
protect_running_kernel
-
Controls whether the package corresponding to the running version of kernel is protected from removal. Default is
True
.
releasever
-
Used for substitution of
$releasever
in the repository configuration.The
$releasever_major
and$releasever_minor
variables will be automatically derived from$releasever
by splitting it on the first.
. For example, if$releasever
is set to1.23
, then$releasever_major
will be1
and$releasever_minor
will be23
.See also repo variables.
reposdir
-
DNF searches for repository configuration files in the paths specified by
reposdir
. The behavior ofreposdir
could differ when it is used along with --installroot option.
rpmverbosity
-
RPM debug scriptlet output level. One of:
critical
,emergency
,error
,warn
,info
ordebug
. Default isinfo
.
strict
-
If disabled, all unavailable packages or packages with broken dependencies given to DNF command will be skipped without raising the error causing the whole operation to fail. Currently works for install command only. The default is True.
tsflags
-
List of strings adding extra flags for the RPM transaction.
tsflag value
RPM Transaction Flag
noscripts
RPMTRANS_FLAG_NOSCRIPTS
test
RPMTRANS_FLAG_TEST

nocontexts
RPMTRANS_FLAG_NOCONTEXTS
nocaps
RPMTRANS_FLAG_NOCAPS
nocrypto
RPMTRANS_FLAG_NOFILEDIGEST
deploops
RPMTRANS_FLAG_DEPLOOPS
The
nocrypto
option will also set the_RPMVSF_NOSIGNATURES
and_RPMVSF_NODIGESTS
VS flags. Thetest
option provides a transaction check without performing the transaction. It includes downloading of packages, gpg keys check (including permanent import of additional keys if necessary), and rpm check to prevent file conflicts. Thenocaps
is supported with rpm-4.14 or later. Whennocaps
is used but rpm doesn’t support it, DNF only reports it as an invalid tsflag.
upgrade_group_objects_upgrade
-
Set this to False to disable the automatic running of
group upgrade
when running theupgrade
command. Default isTrue
(perform the operation).
varsdir
-
List of directories where variables definition files are looked for. Defaults to
"/etc/dnf/vars", "/etc/yum/vars"
. See variable files in Configuration reference. zchunk
-
Enables or disables the use of repository metadata compressed using the zchunk format (if available). Default is
True
.

Repo Options
baseurl
-
List of URLs for the repository. Defaults to
[]
.URLs are tried in the listed order (equivalent to yum’s “failovermethod=priority” behaviour).
cost
-
The relative cost of accessing this repository, defaulting to 1000. This value is compared when the priorities of two repositories are the same. The repository with the lowest cost is picked. It is useful to make the library prefer on-disk repositories to remote ones.
enabled
-
Include this repository as a package source. The default is True.
gpgkey
list of strings
URLs of a GPG key files that can be used for signing metadata and packages of this repository, empty by default. If a file can not be verified using the already imported keys, import of keys from this option is attempted and the keys are then used for verification.
metalink
-
URL of a metalink for the repository. Defaults to
None
.
mirrorlist
-
URL of a mirrorlist for the repository. Defaults to
None
.
module_hotfixes
-
Set this to True to disable module RPM filtering and make all RPMs from the repository available. The default is False. This allows user to create a repository with cherry-picked hotfixes that are included in a package set on a modular system.
name
-
A human-readable name of the repository. Defaults to the ID of the repository.
priority
-
The priority value of this repository, default is 99. If there is more than one candidate package for a particular operation, the one from a repo with the lowest priority value is picked, possibly despite being less convenient otherwise (e.g. by being a lower version).
type
-
Type of repository metadata. Supported values are:
rpm-md
. Aliases forrpm-md
:rpm
,repomd
,rpmmd
,yum
,YUM
.
Source and debuginfo repository names
For a given repository with an identifier in the form “<ID>-rpms”, its corresponding source repository is expected to have an identifier in the form “<ID>-source-rpms” and debuginfo repository an identifier in the form “<ID>-debug-rpms”. Otherwise (if the repository identifier doesn’t have the “-rpms” suffix), the source repository is expected to have an identifier in the form “<ID>-source” and debuginfo repository an identifier in the form “<ID>-debuginfo”.
For example, for repository “fedora”, the source repository is “fedora-source” and debuginfo repository is “fedora-debuginfo”. For repository “fedora-rpms”, the source repository is “fedora-source-rpms” and debuginfo repository is “fedora-debug-rpms”.
Repo Variables
Right side of every repo option can be enriched by the following variables:
$arch
Refers to the system’s CPU architecture e.g, aarch64, i586, i686 and x86_64.
$basearch
Refers to the base architecture of the system. For example, i686 and i586 machines both have a base architecture of i386, and AMD64 and Intel64 machines have a base architecture of x86_64.
$releasever
Refers to the release version of operating system which DNF derives from information available in RPMDB.
$releasever_major
Major version of
$releasever
, i.e. the component of$releasever
occurring before the first.
.
$releasever_minor
Minor version of
$releasever
, i.e. the component of$releasever
occurring after the first.
.
In addition to these hard coded variables, user-defined ones can also be used. They can be defined either via variable files, or by using special environmental variables. The names of these variables must be prefixed with DNF_VAR_ and they can only consist of alphanumeric characters and underscores:
$ DNF_VAR_MY_VARIABLE=value
To use such variable in your repository configuration remove the prefix. E.g.:
[myrepo]
baseurl=https://example.site/pub/fedora/$MY_VARIABLE/releases/$releasever
Note that it is not possible to override the arch
and basearch
variables using either variable files or environmental variables.
Although users are encouraged to use named variables, the numbered environmental variables DNF0
- DNF9
are still supported:
$ DNF1=value
[myrepo]
baseurl=https://example.site/pub/fedora/$DNF1/releases/$releasever
A limited form of shell-like parameter expansion is supported for variables.
${my_variable:-word}
If my_variable
is unset or empty, then word
will be substituted. Otherwise, the value of my_variable
will be substituted.
${my_variable:+word}
If my_variable
is set and not empty, then word
will be substituted. Otherwise, the empty string will be substituted.
Parameter expansions can be nested up to a maximum depth of 32. For example:
${my_defined_variable:+${my_undefined_variable:-foobar}}
will evaluate to foobar
.
Options for both [main] and Repo
Some options can be applied in either the main section, per repository, or in a combination. The value provided in the main section is used for all repositories as the default value, which repositories can then override in their configuration.
bandwidth
storage size
Total bandwidth available for downloading. Meaningful when used with the throttle option. Storage size is in bytes by default but can be specified with a unit of storage. Valid units are ‘k’, ‘M’, ‘G’.
countme
-
When enabled, one (and only one) HTTP GET request for the metalink file will be selected at random every week to carry a special URL flag.
This flag allows the repository provider to estimate the number of systems consuming the repository, by counting such requests over a week’s time. This method is more accurate than just counting unique IP addresses (which is subject to both overcounting and undercounting due to short DHCP leases and NAT, respectively).
This is not an out-of-band HTTP request made for this purpose alone. Only requests initiated by DNF during normal operation, such as to check for metadata updates, can get this flag.
The flag is a simple “countme=N” parameter appended to the metalink URL where N is an integer representing the age “bucket” this system belongs to. Four buckets are defined, based on how many full weeks have passed since the installation of a system:
bucket
system age
1
first week
2
first month (2 - 4 weeks)
3
first 6 months (5 - 24 weeks)
4
more than 6 months (> 24 weeks)
This number is meant to help distinguish short-lived (throwaway) machines from long-term installs and get a better picture of how systems are used over time.
To determine a system’s installation time (“epoch”), the
machine-id(5)
file’s modification time is used as the single source of truth. This file is semantically tied to the system’s lifetime as it’s typically populated at installation time or during the first boot by an installer tool or init system (such assystemd(1)
), respectively, and remains unchanged.If the file is empty or missing (such as in containers), the time of the very first request made using the expanded metalink URL (i.e. with any repository variables such as
$releasever
substituted) that carried the flag is declared as the epoch.If no metalink URL is defined for this repository but a mirrorlist URL is, the latter is used for this purpose instead.
Default is False.
deltarpm
-
When enabled, DNF will save bandwidth by downloading much smaller delta RPM files, rebuilding them to RPM locally. However, this is quite CPU and I/O intensive. Default is False. It requires /usr/bin/applydeltarpm on the system.
deltarpm_percentage
-
When the relative size of delta vs pkg is larger than this, delta is not used. Default value is 75 (Deltas must be at least 25% smaller than the pkg). Use 0 to turn off delta rpm processing. Local repositories (with file:// baseurl) have delta rpms turned off by default.
enablegroups
-
Determines whether DNF will allow the use of package groups for this repository. Default is True (package groups are allowed).
excludepkgs
-
Exclude packages of this repository, specified by a name or a glob and separated by a comma, from all operations. Can be disabled using
--disableexcludes
command line switch. Defaults to[]
.
fastestmirror
-
If enabled, TCP socket latency is used to find the closest available mirror. A mirror is then selected at random with less than twice the lowest latency for load balancing purposes. This overrides the order provided by the mirrorlist/metalink file itself, and does not take into consideration mirrorlist parameters such as mirror bandwidth nor preferred mirrors for client IP addresses.
gpgcheck
-
Whether to perform GPG signature check on packages found in this repository. The default is False.
This option can only be used to strengthen the active RPM security policy set with the
%_pkgverify_level
macro (see the/usr/lib/rpm/macros
file for details). That means, if the macro is set to ‘signature’ or ‘all’ and this option is False, it will be overridden to True during DNF runtime, and a warning will be printed. To squelch the warning, make sure this option is True for every enabled repository, and also enable localpkg_gpgcheck.
includepkgs
-
Include packages of this repository, specified by a name or a glob and separated by a comma, in all operations. Inverse of excludepkgs, DNF will exclude any package in the repository that doesn’t match this list. This works in conjunction with
excludepkgs
and doesn’t override it, so if you ‘excludepkgs=*.i386’ and ‘includepkgs=python*’ then only packages starting with python that do not have an i386 arch will be seen by DNF in this repo. Can be disabled using--disableexcludes
command line switch. Defaults to[]
.
ip_resolve
IP address type
Determines how DNF resolves host names. Set this to ‘4’/’IPv4’ or ‘6’/’IPv6’ to resolve to IPv4 or IPv6 addresses only. By default, DNF resolves to either addresses.
localpkg_gpgcheck
-
Whether to perform a GPG signature check on local packages (packages in a file, not in a repository). The default is False. This option is subject to the active RPM security policy (see gpgcheck for more details).
max_parallel_downloads
-
Maximum number of simultaneous package downloads. Defaults to 3. Maximum of 20.
metadata_expire
time in seconds
The period after which the remote repository is checked for metadata update and in the positive case the local metadata cache is updated. The default corresponds to 48 hours. Set this to
-1
ornever
to make the repo never considered expired. Expire of metadata can be also triggered by change of timestamp of configuration files (dnf.conf
,<repo>.repo
). See also check_config_file_age.
minrate
storage size
This sets the low speed threshold in bytes per second. If the server is sending data at the same or slower speed than this value for at least timeout option seconds, DNF aborts the connection. The default is 1000. Valid units are ‘k’, ‘M’, ‘G’.
password
-
The password to use for connecting to a repository with basic HTTP authentication. Empty by default.
proxy
-
URL of a proxy server to connect through. Set to an empty string in the repository configuration to disable proxy setting inherited from the main section. The expected format of this option is
<scheme>://<ip-or-hostname>[:port]
. (For backward compatibility, ‘_none_’ can be used instead of the empty string.)Note: The curl environment variables (such as
http_proxy
) are effective if this option is unset (or ‘_none_’ is set in the repository configuration). See thecurl
man page for details.
proxy_username
-
The username to use for connecting to the proxy server. Empty by default.
proxy_password
-
The password to use for connecting to the proxy server. Empty by default.
proxy_auth_method
-
The authentication method used by the proxy server. Valid values are
method
meaning
basic
HTTP Basic authentication
digest
HTTP Digest authentication
negotiate
HTTP Negotiate (SPNEGO) authentication
ntlm
HTTP NTLM authentication
digest_ie
HTTP Digest authentication with an IE flavor
ntlm_wb
NTLM delegating to winbind helper
none
None auth method
any
All suitable methods
Defaults to
any
proxy_sslcacert
-
Path to the file containing the certificate authorities to verify proxy SSL certificates. Empty by default - uses system default.
proxy_sslverify
-
When enabled, proxy SSL certificates are verified. If the client can not be authenticated, connecting fails and the repository is not used any further. If
False
, SSL connections can be used, but certificates are not verified. Default isTrue
.
proxy_sslclientcert
-
Path to the SSL client certificate used to connect to proxy server. Empty by default.
proxy_sslclientkey
-
Path to the SSL client key used to connect to proxy server. Empty by default.
repo_gpgcheck
-
Whether to perform GPG signature check on this repository’s metadata. The default is False. Note that GPG keys for this check are stored separately from GPG keys used in package signature verification. Furthermore, they are also stored separately for each repository.
This means that dnf may ask to import the same key multiple times. For example, when a key was already imported for package signature verification and this option is turned on, it may be needed to import it again for the repository.
retries
-
Set the number of total retries for downloading packages. The number is accumulative, so e.g. for retries=10, dnf will fail after any package download fails for eleventh time. Setting this to 0 makes dnf try forever. Default is 10.
sslcacert
-
Path to the file containing the certificate authorities to verify SSL certificates. Empty by default - uses system default.
sslverify
-
When enabled, remote SSL certificates are verified. If the client can not be authenticated, connecting fails and the repository is not used any further. If
False
, SSL connections can be used, but certificates are not verified. Default isTrue
.
sslverifystatus
-
When enabled, revocation status of the server certificate is verified using the “Certificate Status Request” TLS extension (aka. OCSP stapling). Default is
False
.
sslclientcert
-
Path to the SSL client certificate used to connect to remote sites. Empty by default.
sslclientkey
-
Path to the SSL client key used to connect to remote sites. Empty by default.
throttle
storage size
Limits the downloading speed. It might be an absolute value or a percentage, relative to the value of the bandwidth option option.
0
means no throttling (the default). The absolute value is in bytes by default but can be specified with a unit of storage. Valid units are ‘k’, ‘M’, ‘G’.
timeout
time in seconds
Number of seconds to wait for a connection before timing out. Used in combination with minrate option option. Defaults to 30 seconds.
username
-
The username to use for connecting to repo with basic HTTP authentication. Empty by default.
user_agent
-
The User-Agent string to include in HTTP requests sent by DNF. Defaults to
libdnf (NAME VERSION_ID; VARIANT_ID; OS.BASEARCH)
where NAME, VERSION_ID and VARIANT_ID are OS identifiers read from the os-release(5) file, and OS and BASEARCH are the canonical OS name and base architecture, respectively. Example:
libdnf (Fedora 31; server; Linux.x86_64)
Types of Options
