Debian "unattended-upgrade"

Install unattended-upgrade:

apt-get install unattended-upgrades # yep, in plural

Enable the upgrades for all basic system packages:

vi /etc/apt/apt.conf.d/50unattended-upgrades

Contents:

Unattended-Upgrade::Origins-Pattern {
    "o=${distro_id},n=${distro_codename}";
    "o=${distro_id},n=${distro_codename}-updates";
    "o=${distro_id},n=${distro_codename}-proposed-updates";
    "o=${distro_id},n=${distro_codename},l=${distro_id}-Security";
};

Enable automatic upgrades:

vi /etc/apt/apt.conf.d/20auto-upgrades

Contents:

APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";

Or run:

dpkg-reconfigure -plow unattended-upgrades

Test it:

unattended-upgrade -d --dry-run

Third-party repositories

We need the "o= / n= / l=" codes (origin, something and label).

head -10 /var/lib/apt/lists/pkg.jenkins-ci.org_debian_binary_Release

Result:

Architectures: all
Date: Wed, 26 Apr 2017 17:41:15 UTC
Origin: jenkins.io
Suite: binary

This doesn't have a "label", so I used just:

"o=jenkins.io"

Full examples:

Unattended-Upgrade::Origins-Pattern {
      "o=${distro_id},n=${distro_codename}";
      "o=${distro_id},n=${distro_codename}-updates";
      "o=${distro_id},n=${distro_codename}-proposed-updates";
      "o=${distro_id},n=${distro_codename},l=${distro_id}-Security";
      "o=MariaDB,l=MariaDB";
      "o=debmon.org,l=debmon.org";
      "o=jenkins.io";
      "l=gitlab-ci-multi-runner";
  };

Why use third-party packages?

Inevitably Debian folks ask me why I often rely on third-party packages:

  • Sometimes, the package is not available in Debian, obviously.
  • More often, it's for specific packages that roll out new features regularly, in a stable fashion, and where having the latest version is usually strongly recommended. This includes MariaDB, Icinga2, Jenkins and others.
