RootDir = /path/to/root/dir
Set the default root directory for pacman to install to.
This option is used if you want to install a package on a temporary mounted
partition which is "owned" by another system, or for a chroot
install.
NOTE: If database path or log file are not specified on either
the command line or in
pacman.conf(5), their default location will be
inside this root path.
DBPath = /path/to/db/dir
Overrides the default location of the toplevel database
directory. The default is /var/lib/pacman/. Most users will not need to set
this option. NOTE: if specified, this is an absolute path and the root
path is not automatically prepended.
CacheDir = /path/to/cache/dir
Overrides the default location of the package cache
directory. The default is /var/cache/pacman/pkg/. Multiple cache directories
can be specified, and they are tried in the order they are listed in the
config file. If a file is not found in any cache directory, it will be
downloaded to the first cache directory with write access. NOTE: this
is an absolute path, the root path is not automatically prepended.
HookDir = /path/to/hook/dir
Add directories to search for alpm hooks in addition to
the system hook directory (/usr/share/libalpm/hooks/). The default is
/etc/pacman.d/hooks. Multiple directories can be specified with hooks in later
directories taking precedence over hooks in earlier directories.
NOTE:
this is an absolute path, the root path is not automatically prepended. For
more information on the alpm hooks, see
alpm-hooks(5).
GPGDir = /path/to/gpg/dir
Overrides the default location of the directory
containing configuration files for GnuPG. The default is /etc/pacman.d/gnupg/.
This directory should contain two files: pubring.gpg and trustdb.gpg.
pubring.gpg holds the public keys of all packagers. trustdb.gpg contains a
so-called trust database, which specifies that the keys are authentic and
trusted. NOTE: this is an absolute path, the root path is not
automatically prepended.
LogFile = /path/to/log/file
Overrides the default location of the pacman log file.
The default is /var/log/pacman.log. This is an absolute path and the root
directory is not prepended.
HoldPkg = package ...
If a user tries to --remove a package
that’s listed in HoldPkg, pacman will ask for confirmation before
proceeding. Shell-style glob patterns are allowed.
IgnorePkg = package ...
Instructs pacman to ignore any upgrades for this package
when performing a --sysupgrade. Shell-style glob patterns are
allowed.
IgnoreGroup = group ...
Instructs pacman to ignore any upgrades for all packages
in this group when performing a --sysupgrade. Shell-style glob patterns
are allowed.
Include = /path/to/config/file
Include another configuration file. This file can include
repositories or general configuration options. Wildcards in the specified
paths will get expanded based on
glob(7) rules.
Architecture = auto &| i686 &| x86_64 | ...
If set, pacman will only allow installation of packages
with the given architectures (e.g. i686, x86_64, etc). The
special value auto will use the system architecture, provided via
“uname -m”. If unset, no architecture checks are made.
NOTE: Packages with the special architecture any can always be
installed, as they are meant to be architecture independent.
XferCommand = /path/to/command %u
If set, an external program will be used to download all
remote files. All instances of %u will be replaced with the download URL. If
present, instances of %o will be replaced with the local filename, plus a
“.part” extension, which allows programs like wget to do file
resumes properly.
This option is useful for users who experience problems with
built-in HTTP/FTP support, or need the more advanced proxy support that
comes with utilities like wget.
NoUpgrade = file ...
All files listed with a NoUpgrade directive will never be
touched during a package install/upgrade, and the new files will be installed
with a .pacnew extension. These files refer to files in the package
archive, so do not include the leading slash (the RootDir) when specifying
them. Shell-style glob patterns are allowed. It is possible to invert matches
by prepending a file with an exclamation mark. Inverted files will result in
previously blacklisted files being whitelisted again. Subsequent matches will
override previous ones. A leading literal exclamation mark or backslash needs
to be escaped.
NoExtract = file ...
All files listed with a NoExtract directive will never be
extracted from a package into the filesystem. This can be useful when you
don’t want part of a package to be installed. For example, if your
httpd root uses an index.php, then you would not want the
index.html file to be extracted from the apache package. These
files refer to files in the package archive, so do not include the leading
slash (the RootDir) when specifying them. Shell-style glob patterns are
allowed. It is possible to invert matches by prepending a file with an
exclamation mark. Inverted files will result in previously blacklisted files
being whitelisted again. Subsequent matches will override previous ones. A
leading literal exclamation mark or backslash needs to be escaped.
CleanMethod = KeepInstalled &| KeepCurrent
If set to KeepInstalled (the default), the -Sc
operation will clean packages that are no longer installed (not present in the
local database). If set to KeepCurrent, -Sc will clean outdated
packages (not present in any sync database). The second behavior is useful
when the package cache is shared among multiple machines, where the local
databases are usually different, but the sync databases in use could be the
same. If both values are specified, packages are only cleaned if not installed
locally and not present in any known sync database.
SigLevel = ...
Set the default signature verification level. For more
information, see Package and Database Signature Checking below.
LocalFileSigLevel = ...
Set the signature verification level for installing
packages using the "-U" operation on a local file. Uses the value
from SigLevel as the default.
RemoteFileSigLevel = ...
Set the signature verification level for installing
packages using the "-U" operation on a remote file URL. Uses the
value from SigLevel as the default.
UseSyslog
Log action messages through syslog(). This will insert
log entries into /var/log/messages or equivalent.
Color
Automatically enable colors only when pacman’s
output is on a tty.
NoProgressBar
Disables progress bars. This is useful for terminals
which do not support escape characters.
CheckSpace
Performs an approximate check for adequate available disk
space before installing packages.
VerbosePkgLists
Displays name, version and size of target packages
formatted as a table for upgrade, sync and remove operations.
DisableDownloadTimeout
Disable defaults for low speed limit and timeout on
downloads. Use this if you have issues downloading files with proxy and/or
security gateway.
ParallelDownloads
Specifies number of concurrent download streams. The
value needs to be a positive integer. If this config option is not set then
only one download stream is used (i.e. downloads happen sequentially).
Each repository section defines a section name and at least one location where
the packages can be found. The section name is defined by the string within
square brackets (the two above are core and custom). Repository
names must be unique and the name local is reserved for the database of
installed packages. Locations are defined with the Server directive and
follow a URL naming structure. If you want to use a local directory, you can
specify the full path with a “file://” prefix, as shown above.
A common way to define DB locations utilizes the Include
directive. For each repository defined in the configuration file, a single
Include directive can contain a file that lists the servers for that
repository.
[core]
# use this server first
Server = ftp://ftp.archlinux.org/$repo/os/$arch
# next use servers as defined in the mirrorlist below
Include = {sysconfdir}/pacman.d/mirrorlist
The order of repositories in the configuration files matters;
repositories listed first will take precedence over those listed later in
the file when packages in two repositories have identical names, regardless
of version number.
Include = path
Include another config file. This file can include
repositories or general configuration options. Wildcards in the specified
paths will get expanded based on
glob(7) rules.
Server = url
A full URL to a location where the database, packages,
and signatures (if available) for this repository can be found.
During parsing, pacman will define the $repo variable to the name
of the current section. This is often utilized in files specified using the
Include directive so all repositories can use the same mirrorfile.
pacman also defines the $arch variable to the first (or only) value of the
Architecture option, so the same mirrorfile can even be used for different
architectures.
SigLevel = ...
Set the signature verification level for this repository.
For more information, see Package and Database Signature Checking below.
Usage = ...
Set the usage level for this repository. This option
takes a list of tokens which must be at least one of the following:
Sync
Enables refreshes for this repository.
Search
Enables searching for this repository.
Install
Enables installation of packages from this repository
during a --sync operation.
Upgrade
Allows this repository to be a valid source of packages
when performing a --sysupgrade.
All
Enables all of the above features for the repository.
This is the default if not specified.
Note that an enabled repository can be operated on explicitly,
regardless of the Usage level set.
•If set to Never, no signature checking
will take place.
•If set to Optional , signatures will be
checked when present, but unsigned databases and packages will also be
accepted.
•If set to Required, signatures will be
required on all packages and databases.
Alternatively, you can get more fine-grained control by combining
some of the options and prefixes described below. All options in a config
file are processed in top-to-bottom, left-to-right fashion, where later
options override and/or supplement earlier ones. If SigLevel is
specified in a repository section, the starting value is that from the
[options] section, or the built-in system default as shown below if not
specified.
The options are split into two main groups, described below. Terms
used such as “marginally trusted” are terms used by GnuPG, for
more information please consult gpg(1).
When to Check
These options control if and when signature checks should
take place.
Never
All signature checking is suppressed, even if signatures
are present.
Optional (default)
Signatures are checked if present; absence of a signature
is not an error. An invalid signature is a fatal error, as is a signature from
a key not in the keyring.
Required
Signatures are required; absence of a signature or an
invalid signature is a fatal error, as is a signature from a key not in the
keyring.
What is Allowed
These options control what signatures are viewed as
permissible. Note that neither of these options allows acceptance of invalid
or expired signatures, or those from revoked keys.
TrustedOnly (default)
If a signature is checked, it must be in the keyring and
fully trusted; marginal trust does not meet this criteria.
TrustAll
If a signature is checked, it must be in the keyring, but
is not required to be assigned a trust level (e.g., unknown or marginal
trust).
Options in both groups can additionally be prefixed with either
Package or Database, which will cause it to only take effect
on the specified object type. For example, PackageTrustAll would allow
marginal and unknown trust level signatures for packages.
The built-in default is the following:
SigLevel = Optional TrustedOnly
