dnf.conf — 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.

[Main] Options

assumeyes
boolean

If enabled dnf will assume Yes where it would normally prompt for confirmation from user input (see also defaultyes). Default is False.
best
boolean

When upgrading a package, always try to install its highest version available, even only to find out some of its deps are not satisfiable. Enable this if you want to experience broken dependencies in the repositories firsthand. The default is False.
check_config_file_age
boolean

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).
clean_requirements_on_remove
boolean

Remove dependencies that are no longer used during dnf remove. A package only qualifies for removal via clean_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
string

Path to the default main configuration file. Default is /etc/dnf/dnf.conf.
debuglevel
integer

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.
defaultyes
boolean

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 is False.
errorlevel
integer

Error messages output level, in the range 0 to 10. The higher the number the more error output is put to stderr. Default is 2. This is deprecated in DNF and overwritten by --verbose commandline option.
exit_on_lock
boolean

Should the dnf client exit immediately when something else has the lock. Default is False
group_package_types
list

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
install_weak_deps
boolean

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 pulled into the transaction. Default is True.
installonlypkgs
list

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
integer

Number of installonly packages allowed to be installed concurrently. Defaults to 3.
keepcache
boolean

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
string

Directory where the log files will be stored. Default is /var/log.
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 simple makecache run. Use 0 to completely disable automatic metadata synchronizing. The default corresponds to three hours. The value is rounded to the next commenced hour.
pluginconfpath
list

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

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.
protected_packages
list

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 and glob:/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.
reposdir
list

DNF searches for repository configuration files in the paths specified by reposdir. The behavior of reposdir could differ when it is used along with --installroot option.
rpmverbosity
string

RPM debug scriptlet output level. One of: critical, emergency, error, warn, info or debug. Default is info.
upgrade_group_objects_upgrade
boolean

Set this to False to disable the automatic running of group upgrade when running the upgrade command. Default is True (perform the operation).

Repo Options

baseurl
list

URLs for the repository.
cost
integer

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
boolean

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
string

URL of a metalink for the repository.
mirrorlist
string

URL of a mirrorlist for the repository.
name
string

A human-readable name of the repository. Defaults to the ID of the repository.
priority
integer

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).
retries
integer

Overrides the retries option from the [main] section for this repository.
skip_if_unavailable
boolean

If enabled, DNF will continue running and disable the repository that couldn't be contacted for any reason when downloading metadata. This option doesn't affect skipping of unavailable packages after dependency resolution. To check inaccessibility of repository use it in combination with refresh command line option. The default is True.
strict
boolean

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.
type
string

Type of repository metadata. Supported values are: rpm-md. Aliases for rpm-md: rpm, repomd, rpmmd, yum, YUM.

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.

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 and concrete repositories can override it 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'.
deltarpm
boolean

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 True.
deltarpm_percentage

integer

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
boolean

Determines whether DNF will allow the use of package groups for this repository. Default is True (package groups are allowed).
excludepkgs
list

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.
fastestmirror
boolean

If enabled a metric is used to find the fastest available mirror. This overrides the order provided by the mirrorlist/metalink file itself. This file is often dynamically generated by the server to provide the best download speeds and enabling fastestmirror overrides this. The default is False.
gpgcheck
boolean

Whether to perform GPG signature check on packages found in this repository. The default is False.
includepkgs
list

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 exclude 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.
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
boolean

Whether to perform a GPG signature check on local packages (packages in a file, not in a repositoy). The default is False.
max_parallel_downloads
integer

Maximum number of simultaneous package downloads. Defaults to 3.
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 or never to make the repo never considered expired.
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'.
proxy
string

URL of a proxy server to connect through. If none is specified then direct connection is used (the default).
proxy_username
string

The username to use for connecting to the proxy server. Empty by default.
proxy_password
string

The password to use for connecting to the proxy server. Empty by default.
repo_gpgcheck
boolean

Whether to perform GPG signature check on this repository's metadata. The default is False.
retries

integer

Set the number of times any attempt to retrieve a file should retry before returning an error. Setting this to

`

0' makes dnf try forever. Default is

`

10'.

sslcacert
string

Path to the directory or file containing the certificate authorities to verify SSL certificates. Empty by default - uses system default.
sslverify
boolean

When enabled, remote SSL connections are verified. If the client can not be authenticated connecting fails and the given repo is not used further. On False, SSL connections can be used but are not verified. Default is True.
sslclientcert
string

Path to the SSL client certificate used to connect to remote sites. Empty by default.
sslclientkey
string

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 120 seconds.
username
string

The username to use for connecting to repo with basic HTTP authentication. Empty by default.
password
string

The password to use for connecting to repo with basic HTTP authentication. Empty by default.

Types of Options

boolean
This is a data type with only two possible values.

One of following options can be used: 1, 0, True, False, yes, no
integer
It is a whole number that can be written without a fractional component.
list
It is an option that could represent one or more strings separated by space or comma characters.
string
It is a sequence of symbols or digits without any whitespace character.
