WIP: refactoring of https://wiki.debian.org/AptConf and other apt configuration pages

Apt is configured by several resources, including:

  • command-line options

  • ?AptKeys

  • apt_preferences

  • AptSources

  • apt.conf

apt.conf

See man 5 apt.conf

Apt accepts configuration files (without extension) in /etc/apt/apt.conf.d/. These are processed by Apt in numeric/alphabetical order. /etc/apt/apt.conf is also valid but deprecated.

These files can contain various directives:

  • Dpkg::Pre-Install-Pkgs {"mycommand";};: executes mycommand before package installation/unpacking by Dpkg.

  • Dpkg::Pre-Invoke {"mycommand";};: executes mycommand before apt calls dpkg

  • Dpkg::Post-Invoke {"mycommand";};: executes mycommand after apt calls dpkg

  • Pre-Install-Pkgs: ??? TODO

  • APT::Default-Release "testing";: sets the default Debian release used by Apt (TODO use case?)

  • APT::Cache-Limit 10000000;: ??? TODO

  • Apt::Get::Purge;: ??? TODO

  • Acquire::http::Proxy "http://proxy:8080";: sets the proxy for HTTP downloads

  • Acquire::https::Proxy "https://proxy:8443";: sets the proxy for HTTPS downloads

  • Acquire::http::Timeout "2";: sets the timeout for HTTP downloads

  • Acquire::https::Timeout "2";: sets the timeout for HTTPS downloads

  • Acquire::ftp::Timeout "2";: sets the timeout for FTP downloads

If you really have to use FTP, this sets the FTP proxy: 

 Acquire::ftp
 {
   Proxy "ftp://proxy:2121/";
   ProxyLogin
   {
      "USER $(SITE_USER)@$(SITE)";
      "PASS $(SITE_PASS)";
   }
 }

apt_preferences

See man 5 apt_preferences

Command line options

PackageManagementTools such as apt, aptitude, apt-get... allow you to set specific configuration options for a single run. See their respective ?ManPages.
