// Unattended-Upgrade::Origins-Pattern controls which packages are // upgraded. // // Lines below have the format "keyword=value,...". A // package will be upgraded only if the values in its metadata match // all the supplied keywords in a line. (In other words, omitted // keywords are wild cards.) The keywords originate from the Release // file, but several aliases are accepted. The accepted keywords are: // a,archive,suite (eg, "stable") // c,component (eg, "main", "contrib", "non-free") // l,label (eg, "Debian", "Debian-Security") // o,origin (eg, "Debian", "Unofficial Multimedia Packages") // n,codename (eg, "jessie", "jessie-updates") // site (eg, "http.debian.net") // The available values on the system are printed by the command // "apt-cache policy", and can be debugged by running // "unattended-upgrades -d" and looking at the log file. // // Within lines unattended-upgrades allows 2 macros whose values are // derived from /etc/debian_version: // ${distro_id} Installed origin. // ${distro_codename} Installed codename (eg, "buster") Unattended-Upgrade::Origins-Pattern { // Codename based matching: // This will follow the migration of a release through different // archives (e.g. from testing to stable and later oldstable). // Software will be the latest available for the named release, // but the Debian release itself will not be automatically upgraded. // "origin=Debian,codename=${distro_codename}-updates"; // "origin=Debian,codename=${distro_codename}-proposed-updates"; "origin=Debian,codename=${distro_codename},label=Debian"; "origin=Debian,codename=${distro_codename},label=Debian-Security"; "origin=Debian,codename=${distro_codename}-security,label=Debian-Security"; // Archive or Suite based matching: // Note that this will silently match a different release after // migration to the specified archive (e.g. testing becomes the // new stable). // "o=Debian,a=stable"; // "o=Debian,a=stable-updates"; // "o=Debian,a=proposed-updates"; // "o=Debian Backports,a=${distro_codename}-backports,l=Debian Backports"; }; // Python regular expressions, matching packages to exclude from upgrading Unattended-Upgrade::Package-Blacklist { // The following matches all packages starting with linux- // "linux-"; // Use $ to explicitely define the end of a package name.
