{{Header}} {{Box|text= {{{package}}} can be installed from Debian backports. This is non-ideal; see the footnote. {{Prefer_stable_APT}} {{IconSet|h2|1}} Boot {{project_name_workstation_long}} ({{project_name_workstation_template}}) Template. {{IconSet|h2|2}} Add the current Debian stable backports codename {{Stable_project_version_based_on_Debian_codename}}-backports to Debian apt sources. Note: this applies to {{project_name_short}} {{VersionNew}}. Later {{project_name_short}} versions may use a codename different from {{Stable_project_version_based_on_Debian_codename}}. In {{project_name_workstation_short}} ({{project_name_workstation_template}}) Template, run. {{CodeSelect|code= sudo su -c "echo -e 'Types: deb URIs: tor+https://deb.debian.org/debian Suites: {{Stable_project_version_based_on_Debian_codename}}-backports Components: main contrib non-free Enabled: yes Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg' > /etc/apt/sources.list.d/backports.sources" }} Alternatively, users who like [[Onionizing Repositories]] can set the .onion mirror. {{CodeSelect|code= sudo su -c "echo -e 'Types: deb URIs: tor+http://{{Debian_onion}}/debian Suites: {{Stable_project_version_based_on_Debian_codename}}-backports Components: main contrib non-free Enabled: yes Signed-By: /usr/share/keyrings/debian-archive-keyring.gpg' > /etc/apt/sources.list.d/backports.sources" }} {{IconSet|h2|3}} [[Operating_System_Software_and_Updates#Updates|Update]] the package lists. {{CodeSelect|code= sudo apt update }} {{IconSet|h2|4}} Install the selected software. {{CodeSelect|code= sudo apt -t {{Stable_project_version_based_on_Debian_codename}}-backports install {{{package}}} }} The procedure is now complete. {{IconSet|h2|5}} Undo. On occasion it is necessary to undo this configuration, for example when upgrading from Debian {{Stable_project_version_based_on_Debian_codename}} to {{Debian_Codename_Testing}}. Most often this step applies before attempting major {{project_name_short}} upgrades; upgrade instructions are also made available at that time (see [[Stay_Tuned|Stay Tuned]]). To proceed, run. {{CodeSelect|code= sudo rm /etc/apt/sources.list.d/backports.sources }} }} = Footnotes = {{Footer}}
