9 pacman.conf - pacman package manager configuration file
14 {sysconfdir}/pacman.conf
19 Pacman, using linkman:libalpm[3], will attempt to read pacman.conf each time it
20 is invoked. This configuration file is divided into sections or repositories.
21 Each section defines a package repository that pacman can use when searching
22 for packages in '\--sync' mode. The exception to this is the options section,
23 which defines global options.
34 NoUpgrade = etc/passwd etc/group etc/shadow
38 Include = /etc/pacman.d/core
41 Server = file:///home/pkgs
44 NOTE: Each directive must be in CamelCase. If the case isn't respected, the
45 directive won't be recognized. For example. noupgrade or NOUPGRADE will not
50 *RootDir =* path/to/root::
51 Set the default root directory for pacman to install to. This option is
52 used if you want to install a package on a temporary mounted partition
53 which is "owned" by another system, or for a chroot install.
54 *NOTE*: If database path or logfile are not specified on either the
55 command line or in linkman:pacman.conf[5], their default location will
56 be inside this root path.
58 *DBPath =* path/to/db/dir::
59 Overrides the default location of the toplevel database directory. A
60 typical default is +{localstatedir}/lib/pacman/+. Most users will not need to set
61 this option. *NOTE*: if specified, this is an absolute path and the root
62 path is not automatically prepended.
64 *CacheDir =* path/to/cache/dir::
65 Overrides the default location of the package cache directory. A typical
66 default is +{localstatedir}/cache/pacman/pkg/+. Multiple cache directories can be
67 specified, and they are tried in the order they are listed in the config
68 file. If a file is not found in any cache directory, it will be downloaded
69 to the first cache directory with write access. *NOTE*: this is an absolute
70 path, the root path is not automatically prepended.
72 *GPGDir =* path/to/gpg/dir::
73 Overrides the default location of the directory containing configuration
74 files for GnuPG. A typical default is +{sysconfdir}/pacman.d/gnupg/+.
75 This directory should contain two files: `pubring.gpg` and `trustdb.gpg`.
76 `pubring.gpg` holds the public keys of all packagers. `trustdb.gpg`
77 contains a so-called trust database, which specifies that the keys are
78 authentic and trusted.
79 *NOTE*: this is an absolute path, the root path is not automatically
82 *LogFile =* '/path/to/file'::
83 Overrides the default location of the pacman log file. A typical default
84 is +{localstatedir}/log/pacman.log+. This is an absolute path and the root directory
87 *HoldPkg =* package ...::
88 If a user tries to '\--remove' a package that's listed in `HoldPkg`,
89 pacman will ask for confirmation before proceeding. Shell-style glob
92 *IgnorePkg =* package ...::
93 Instructs pacman to ignore any upgrades for this package when performing
94 a '\--sysupgrade'. Shell-style glob patterns are allowed.
96 *IgnoreGroup =* group ...::
97 Instructs pacman to ignore any upgrades for all packages in this
98 group when performing a '\--sysupgrade'. Shell-style glob patterns are
102 Include another config file. This file can include repositories or
103 general configuration options. Wildcards in the specified paths will get
104 expanded based on linkman:glob[7] rules.
106 *Architecture =* auto | i686 | x86_64 | ...::
107 If set, pacman will only allow installation of packages of the given
108 architecture (e.g. 'i686', 'x86_64', etc). The special value 'auto' will
109 use the system architecture, provided by in ``uname -m''. If unset, no
110 architecture checks are made. *NOTE*: packages with the special
111 architecture 'any' can always be installed, as they are meant to be
112 architecture independent.
114 *XferCommand =* /path/to/command %u::
115 If set, an external program will be used to download all remote files.
116 All instances of `%u` will be replaced with the download URL. If present,
117 instances of `%o` will be replaced with the local filename, plus a
118 ``.part'' extension, which allows programs like wget to do file resumes
121 This option is useful for users who experience problems with built-in
122 http/ftp support, or need the more advanced proxy support that comes with
125 *NoUpgrade =* file ...::
126 All files listed with a `NoUpgrade` directive will never be touched during
127 a package install/upgrade, and the new files will be installed with a
129 These files refer to files in the package archive, so do not include the
130 leading slash (the RootDir) when specifying them. Shell-style glob patterns
133 *NoExtract =* file ...::
134 All files listed with a `NoExtract` directive will never be extracted from
135 a package into the filesystem. This can be useful when you don't want part
136 of a package to be installed. For example, if your httpd root uses an
137 'index.php', then you would not want the 'index.html' file to be extracted
138 from the 'apache' package.
139 These files refer to files in the package archive, so do not include the
140 leading slash (the RootDir) when specifying them. Shell-style glob patterns
143 *CleanMethod =* KeepInstalled &| KeepCurrent::
144 If set to `KeepInstalled` (the default), the '-Sc' operation will clean
145 packages that are no longer installed (not present in the local database).
146 If set to `KeepCurrent`, '-Sc' will clean outdated packages (not present in
148 The second behavior is useful when the package cache is shared among
149 multiple machines, where the local databases are usually different, but the
150 sync databases in use could be the same. If both values are specified,
151 packages are only cleaned if not installed locally and not present in any
155 Set the default signature verification level. For more information, see
156 <<SC,Package and Database Signature Checking>> below.
159 Log action messages through syslog(). This will insert log entries into
160 +{localstatedir}/log/messages+ or equivalent.
162 *UseDelta* [= ratio]::
163 Download delta files instead of complete packages if possible. Requires
164 the `xdelta3` program to be installed. If a ratio is specified (e.g.,
165 `0.5`), then it is used as a cutoff for determining whether to use deltas.
166 Allowed values are between `0.0` and `2.0`; sensible values are between
167 `0.2` and `0.9`. Using a value above `1.0` is not recommended. The
168 default is `0.7` if left unspecified.
171 When downloading, display the amount downloaded, download rate, ETA,
172 and completed percentage of the entire download list rather
173 than the percent of each individual download target. The progress
174 bar is still based solely on the current file download.
177 Performs an approximate check for adequate available disk space before
181 Displays name, version and size of target packages formatted
182 as a table for upgrade, sync and remove operations.
186 Each repository section defines a section name and at least one location where
187 the packages can be found. The section name is defined by the string within
188 square brackets (the two above are 'current' and 'custom'). Locations are
189 defined with the 'Server' directive and follow a URL naming structure. If you
190 want to use a local directory, you can specify the full path with a ``file://''
191 prefix, as shown above.
193 A common way to define DB locations utilizes the 'Include' directive. For each
194 repository defined in the configuration file, a single 'Include' directive can
195 contain a file that lists the servers for that repository.
199 # use this server first
200 Server = ftp://ftp.archlinux.org/$repo/os/$arch
201 # next use servers as defined in the mirrorlist below
202 Include = {sysconfdir}/pacman.d/mirrorlist
205 The order of repositories in the configuration files matters; repositories
206 listed first will take precedence over those listed later in the file when
207 packages in two repositories have identical names, regardless of version
211 Include another config file. This file can include repositories or
212 general configuration options. Wildcards in the specified paths will get
213 expanded based on linkman:glob[7] rules.
216 A full URL to a location where the database, packages, and signatures (if
217 available) for this repository can be found.
219 During parsing, pacman will define the `$repo` variable to the name of the
220 current section. This is often utilized in files specified using the 'Include'
221 directive so all repositories can use the same mirrorfile. pacman also defines
222 the `$arch` variable to the value of `Architecture`, so the same mirrorfile can
223 even be used for different architectures.
226 Set the signature verification level for this repository. For more
227 information, see <<SC,Package and Database Signature Checking>> below.
229 Package and Database Signature Checking
230 ---------------------------------------
231 The 'SigLevel' directive is valid in both the `[options]` and repository
232 sections. If used in `[options]`, it sets a default value for any repository
233 that does not provide the setting.
235 * If set to *Never*, no signature checking will take place.
236 * If set to *Optional* , signatures will be checked when present, but unsigned
237 databases and packages will also be accepted.
238 * If set to *Required*, signatures will be required on all packages and
241 Alternatively, you can get more fine-grained control by combining some of
242 the options and prefixes described below. All options in a config file are
243 processed in top-to-bottom, left-to-right fashion, where later options override
244 and/or supplement earlier ones. If 'SigLevel' is specified in a repository
245 section, the starting value is that from the `[options]` section, or the
246 built-in system default as shown below if not specified.
248 The options are split into two main groups, described below. Terms used such as
249 ``marginally trusted'' are terms used by GnuPG, for more information please
250 consult linkman:gpg[1].
253 These options control if and when signature checks should take place.
256 All signature checking is suppressed, even if signatures are present.
258 *Optional* (default);;
259 Signatures are checked if present; absence of a signature is not an
260 error. An invalid signature is a fatal error, as is a signature from a
261 key not in the keyring.
264 Signatures are required; absence of a signature or an invalid signature
265 is a fatal error, as is a signature from a key not in the keyring.
268 These options control what signatures are viewed as permissible. Note that
269 neither of these options allows acceptance of invalid or expired
270 signatures, or those from revoked keys.
272 *TrustedOnly* (default);;
273 If a signature is checked, it must be in the keyring and fully trusted;
274 marginal trust does not meet this criteria.
277 If a signature is checked, it must be in the keyring, but is not
278 required to be assigned a trust level (e.g., unknown or marginal
281 Options in both groups can additionally be prefixed with either *Package* or
282 *Database*, which will cause it to only take effect on the specified object
283 type. For example, `PackageTrustAll` would allow marginal and unknown trust
284 level signatures for packages.
286 The built-in default is the following:
289 SigLevel = Optional TrustedOnly
292 Using Your Own Repository
293 -------------------------
294 If you have numerous custom packages of your own, it is often easier to generate
295 your own custom local repository than install them all with the '\--upgrade'
296 option. All you need to do is generate a compressed package database in the
297 directory with these packages so pacman can find it when run with '\--refresh'.
299 repo-add /home/pkgs/custom.db.tar.gz /home/pkgs/*.pkg.tar.gz
301 The above command will generate a compressed database named
302 '/home/pkgs/custom.db.tar.gz'. Note that the database must be of the form
303 '\{treename\}.db.tar.{ext}', where '\{treename\}' is the name of the section
304 defined in the configuration file and '\{ext\}' is a valid compression type as
305 documented in linkman:repo-add[8]. That's it! Now configure your custom section
306 in the configuration file as shown in the config example above. Pacman will now
307 use your package repository. If you add new packages to the repository,
308 remember to re-generate the database and use pacman's '\--refresh' option.
