When an APT tool starts up it will - read the configuration specified by the <envar/APT_CONFIG/ environment - variable (if any) and then read the files in <literal/Dir::Etc::Parts/ - then read the main configuration file specified by - <literal/Dir::Etc::main/ then finally apply the - command line options to override the configuration directives, possibly - loading even more config files. - <para> - The configuration file is organized in a tree with options organized into - functional groups. Option specification is given with a double colon - notation, for instance <literal/APT::Get::Assume-Yes/ is an option within - the APT tool group, for the Get tool. Options do not inherit from their - parent groups. - <para> - Syntacticly the configuration language is modeled after what the ISC tools - such as bind and dhcp use. Lines starting with - <literal>//</literal> are treated as comments (ignored). Each line is of the form - <literallayout>APT::Get::Assume-Yes "true";</literallayout> The trailing - semicolon is required and the quotes are optional. A new scope can be - opened with curly braces, like: -<informalexample><programlisting> -APT { - Get { - Assume-Yes "true"; - Fix-Broken "true"; - }; -}; -</programlisting></informalexample> - with newlines placed to make it more readable. Lists can be created by - opening a scope and including a single word enclosed in quotes followed by a - semicolon. Multiple entries can be included, each separated by a semicolon. -<informalexample><programlisting> -DPkg::Pre-Install-Pkgs {"/usr/sbin/dpkg-preconfigure --apt";}; -</programlisting></informalexample> - <para> - In general the sample configuration file in - <filename>&docdir;examples/apt.conf</> &configureindex; - is a good guide for how it should look. - <para> - Two specials are allowed, <literal/#include/ and <literal/#clear/. - <literal/#include/ will include the given file, unless the filename - ends in a slash, then the whole directory is included. - <literal/#clear/ is used to erase a list of names. - <para> - All of the APT tools take a -o option which allows an arbitrary configuration - directive to be specified on the command line. The syntax is a full option - name (<literal/APT::Get::Assume-Yes/ for instance) followed by an equals - sign then the new value of the option. Lists can be appended too by adding - a trailing :: to the list name. - </RefSect1> - - <RefSect1><Title>The APT Group</> - <para> - This group of options controls general APT behavior as well as holding the - options for all of the tools. - - <VariableList> - <VarListEntry><Term>Architecture</Term> - <ListItem><Para> - System Architecture; sets the architecture to use when fetching files and - parsing package lists. The internal default is the architecture apt was - compiled for. - </VarListEntry> - - <VarListEntry><Term>Ignore-Hold</Term> - <ListItem><Para> - Ignore Held packages; This global option causes the problem resolver to - ignore held packages in its decision making. - </VarListEntry> - - <VarListEntry><Term>Clean-Installed</Term> - <ListItem><Para> - Defaults to on. When turned on the autoclean feature will remove any packages - which can no longer be downloaded from the cache. If turned off then - packages that are locally installed are also excluded from cleaning - but - note that APT provides no direct means to reinstall them. - </VarListEntry> - - <VarListEntry><Term>Immediate-Configure</Term> - <ListItem><Para> - Disable Immediate Configuration; This dangerous option disables some - of APT's ordering code to cause it to make fewer dpkg calls. Doing - so may be necessary on some extremely slow single user systems but - is very dangerous and may cause package install scripts to fail or worse. - Use at your own risk. - </VarListEntry> - - <VarListEntry><Term>Force-LoopBreak</Term> - <ListItem><Para> - Never Enable this option unless you -really- know what you are doing. It - permits APT to temporarily remove an essential package to break a - Conflicts/Conflicts or Conflicts/Pre-Depend loop between two essential - packages. SUCH A LOOP SHOULD NEVER EXIST AND IS A GRAVE BUG. This option - will work if the essential packages are not tar, gzip, libc, dpkg, bash or - anything that those packages depend on. - </VarListEntry> - - <VarListEntry><Term>Cache-Limit</Term> - <ListItem><Para> - APT uses a fixed size memory mapped cache file to store the 'available' - information. This sets the size of that cache. - </VarListEntry> - - <VarListEntry><Term>Build-Essential</Term> - <ListItem><Para> - Defines which package(s) are considered essential build dependencies. - </VarListEntry> - - <VarListEntry><Term>Get</Term> - <ListItem><Para> - The Get subsection controls the &apt-get; tool, please see its - documentation for more information about the options here. - </VarListEntry> - - <VarListEntry><Term>Cache</Term> - <ListItem><Para> - The Cache subsection controls the &apt-cache; tool, please see its - documentation for more information about the options here. - </VarListEntry> - - <VarListEntry><Term>CDROM</Term> - <ListItem><Para> - The CDROM subsection controls the &apt-cdrom; tool, please see its - documentation for more information about the options here. - </VarListEntry> - </VariableList> - </RefSect1> - - <RefSect1><Title>The Acquire Group</> - <para> - The <literal/Acquire/ group of options controls the download of packages - and the URI handlers. - - <VariableList> - <VarListEntry><Term>Queue-Mode</Term> - <ListItem><Para> - Queuing mode; <literal/Queue-Mode/ can be one of <literal/host/ or - <literal/access/ which determines how APT parallelizes outgoing - connections. <literal/host/ means that one connection per target host - will be opened, <literal/access/ means that one connection per URI type - will be opened. - </VarListEntry> - - <VarListEntry><Term>Retries</Term> - <ListItem><Para> - Number of retries to perform. If this is non-zero APT will retry failed - files the given number of times. - </VarListEntry> - - <VarListEntry><Term>Source-Symlinks</Term> - <ListItem><Para> - Use symlinks for source archives. If set to true then source archives will - be symlinked when possible instead of copying. True is the default - </VarListEntry> - - <VarListEntry><Term>http</Term> - <ListItem><Para> - HTTP URIs; http::Proxy is the default http proxy to use. It is in the - standard form of <literal>http://[[user][:pass]@]host[:port]/</>. Per - host proxies can also be specified by using the form - <literal/http::Proxy::<host>/ with the special keyword <literal/DIRECT/ - meaning to use no proxies. The <envar/http_proxy/ environment variable - will override all settings. - <para> - Three settings are provided for cache control with HTTP/1.1 compliant - proxy caches. <literal/No-Cache/ tells the proxy to not use its cached - response under any circumstances, <literal/Max-Age/ is sent only for - index files and tells the cache to refresh its object if it is older than - the given number of seconds. Debian updates its index files daily so the - default is 1 day. <literal/No-Store/ specifies that the cache should never - store this request, it is only set for archive files. This may be useful - to prevent polluting a proxy cache with very large .deb files. Note: - Squid 2.0.2 does not support any of these options. - <para> - The option <literal/timeout/ sets the timeout timer used by the method, - this applies to all things including connection timeout and data timeout. - <para> - One setting is provided to control the pipeline depth in cases where the - remote server is not RFC conforming or buggy (such as Squid 2.0.2) - <literal/Acquire::http::Pipeline-Depth/ can be a value from 0 to 5 - indicating how many outstanding requests APT should send. A value of - zero MUST be specified if the remote host does not properly linger - on TCP connections - otherwise data corruption will occur. Hosts which - require this are in violation of RFC 2068. - </VarListEntry> - - <VarListEntry><Term>ftp</Term> - <ListItem><Para> - FTP URIs; ftp::Proxy is the default proxy server to use. It is in the - standard form of <literal>ftp://[[user][:pass]@]host[:port]/</> and is - overridden by the <envar/ftp_proxy/ environment variable. To use a ftp - proxy you will have to set the <literal/ftp::ProxyLogin/ script in the - configuration file. This entry specifies the commands to send to tell - the proxy server what to connect to. Please see - &configureindex; for an example of - how to do this. The subsitution variables available are - <literal/$(PROXY_USER)/, <literal/$(PROXY_PASS)/, <literal/$(SITE_USER)/, - <literal/$(SITE_PASS)/, <literal/$(SITE)/, and <literal/$(SITE_PORT)/. - Each is taken from it's respective URI component. - <para> - The option <literal/timeout/ sets the timeout timer used by the method, - this applies to all things including connection timeout and data timeout. - <para> - Several settings are provided to control passive mode. Generally it is - safe to leave passive mode on, it works in nearly every environment. - However some situations require that passive mode be disabled and port - mode ftp used instead. This can be done globally, for connections that - go through a proxy or for a specific host (See the sample config file - for examples) - <para> - It is possible to proxy FTP over HTTP by setting the <envar/ftp_proxy/ - environment variable to a http url - see the discussion of the http method - above for syntax. You cannot set this in the configuration file and it is - not recommended to use FTP over HTTP due to its low efficiency. - <para> - The setting <literal/ForceExtended/ controls the use of RFC2428 - <literal/EPSV/ and <literal/EPRT/ commands. The defaut is false, which means - these commands are only used if the control connection is IPv6. Setting this - to true forces their use even on IPv4 connections. Note that most FTP servers - do not support RFC2428. - </VarListEntry> - - <VarListEntry><Term>cdrom</Term> - <ListItem><Para> - CDROM URIs; the only setting for CDROM URIs is the mount point, - <literal/cdrom::Mount/ which must be the mount point for the CDROM drive - as specified in <filename>/etc/fstab</>. It is possible to provide - alternate mount and unmount commands if your mount point cannot be listed - in the fstab (such as an SMB mount and old mount packages). The syntax - is to put <literallayout>"/cdrom/"::Mount "foo";</literallayout> within - the cdrom block. It is important to have the trailing slash. Unmount - commands can be specified using UMount. - </VarListEntry> - </VariableList> - </RefSect1> - - <RefSect1><Title>Directories</> - <para> - The <literal/Dir::State/ section has directories that pertain to local - state information. <literal/lists/ is the directory to place downloaded - package lists in and <literal/status/ is the name of the dpkg status file. - <literal/preferences/ is the name of the APT preferences file. - <literal/Dir::State/ contains the default directory to prefix on all sub - items if they do not start with <filename>/</> or <filename>./</>. - <para> - <literal/Dir::Cache/ contains locations pertaining to local cache - information, such as the two package caches <literal/srcpkgcache/ and - <literal/pkgcache/ as well as the location to place downloaded archives, - <literal/Dir::Cache::archives/. Generation of caches can be turned off - by setting their names to be blank. This will slow down startup but - save disk space. It is probably prefered to turn off the pkgcache rather - than the srcpkgcache. Like <literal/Dir::State/ the default - directory is contained in <literal/Dir::Cache/ - <para> - <literal/Dir::Etc/ contains the location of configuration files, - <literal/sourcelist/ gives the location of the sourcelist and - <literal/main/ is the default configuration file (setting has no effect, - unless it is done from the config file specified by - <envar/APT_CONFIG/). - <para> - The <literal/Dir::Parts/ setting reads in all the config fragments in - lexical order from the directory specified. After this is done then the - main config file is loaded. - <para> - Binary programs are pointed to by <literal/Dir::Bin/. <literal/Dir::Bin::Methods/ - specifies the location of the method handlers and <literal/gzip/, - <literal/dpkg/, <literal/apt-get/, <literal/dpkg-source/, - <literal/dpkg-buildpackage/ and <literal/apt-cache/ specify the location - of the respective programs. - </RefSect1> - - <RefSect1><Title>APT in DSelect</> - <para> - When APT is used as a &dselect; method several configuration directives - control the default behaviour. These are in the <literal/DSelect/ section. - - <VariableList> - <VarListEntry><Term>Clean</Term> - <ListItem><Para> - Cache Clean mode; this value may be one of always, prompt, auto, - pre-auto and never. always and prompt will remove all packages from - the cache after upgrading, prompt (the default) does so conditionally. - auto removes only those packages which are no longer downloadable - (replaced with a new version for instance). pre-auto performs this - action before downloading new packages. - </VarListEntry> - - <VarListEntry><Term>Options</Term> - <ListItem><Para> - The contents of this variable is passed to &apt-get; as command line - options when it is run for the install phase. - </VarListEntry> - - <VarListEntry><Term>UpdateOptions</Term> - <ListItem><Para> - The contents of this variable is passed to &apt-get; as command line - options when it is run for the update phase. - </VarListEntry> - - <VarListEntry><Term>PromptAfterUpdate</Term> - <ListItem><Para> - If true the [U]pdate operation in &dselect; will always prompt to continue. - The default is to prompt only on error. - </VarListEntry> - </VariableList> - </RefSect1> - - <RefSect1><Title>How APT calls dpkg</> - <para> - Several configuration directives control how APT invokes &dpkg;. These are - in the <literal/DPkg/ section. - - <VariableList> - <VarListEntry><Term>Options</Term> - <ListItem><Para> - This is a list of options to pass to dpkg. The options must be specified - using the list notation and each list item is passed as a single argument - to &dpkg;. - </VarListEntry> - - <VarListEntry><Term>Pre-Invoke</Term><Term>Post-Invoke</Term> - <ListItem><Para> - This is a list of shell commands to run before/after invoking &dpkg;. - Like <literal/Options/ this must be specified in list notation. The - commands are invoked in order using <filename>/bin/sh</>, should any - fail APT will abort. - </VarListEntry> - - <VarListEntry><Term>Pre-Install-Pkgs</Term> - <ListItem><Para> - This is a list of shell commands to run before invoking dpkg. Like - <literal/Options/ this must be specified in list notation. The commands - are invoked in order using <filename>/bin/sh</>, should any fail APT - will abort. APT will pass to the commands on standard input the - filenames of all .deb files it is going to install, one per line. - <para> - Version 2 of this protocol dumps more information, including the - protocol version, the APT configuration space and the packages, files - and versions being changed. Version 2 is enabled by setting - <literal/DPkg::Tools::Options::cmd::Version/ to 2. <literal/cmd/ is a - command given to <literal/Pre-Install-Pkgs/. - </VarListEntry> - - <VarListEntry><Term>Run-Directory</Term> - <ListItem><Para> - APT chdirs to this directory before invoking dpkg, the default is - <filename>/</>. - </VarListEntry> - - <VarListEntry><Term>Build-Options</Term> - <ListItem><Para> - These options are passed to &dpkg-buildpackage; when compiling packages, - the default is to disable signing and produce all binaries. - </VarListEntry> - </VariableList> - </RefSect1> - - <RefSect1><Title>Debug Options</> - <para> - Most of the options in the <literal/debug/ section are not interesting to - the normal user, however <literal/Debug::pkgProblemResolver/ shows - interesting output about the decisions dist-upgrade makes. - <literal/Debug::NoLocking/ disables file locking so APT can do some - operations as non-root and <literal/Debug::pkgDPkgPM/ will print out the - command line for each dpkg invokation. <literal/Debug::IdentCdrom/ will - disable the inclusion of statfs data in CDROM IDs. - </RefSect1> - - <RefSect1><Title>Examples</> - <para> - &configureindex; contains a - sample configuration file showing the default values for all possible - options. - </RefSect1> - - <RefSect1><Title>Files</> - <para> - <filename>/etc/apt/apt.conf</> - </RefSect1> - - <RefSect1><Title>See Also</> - <para> - &apt-cache;, &apt-config;<!-- ? reading apt.conf -->, &apt-preferences;. - </RefSect1> - - &manbugs; - &manauthor; - -</refentry> -- cgit v1.2.3
