Prüfen ob automatische Updates konfiguriert sind:

# aptitude search unattended-upgrades
i   unattended-upgrades

# cat /etc/apt/apt.conf.d/20auto-upgrades
APT::Periodic::Update-Package-Lists "1";
APT::Periodic::Unattended-Upgrade "1";

# cat /etc/apt/apt.conf.d/50unattended-upgrades
// Automatically upgrade packages from these (origin, archive) pairs
Unattended-Upgrade::Allowed-Origins {
      "Ubuntu lucid-security";
//      "Ubuntu lucid-updates";
};

# vi /etc/apt/apt.conf.d/51unattended-upgrades-mail
              Unattended-Upgrade::Mail "Updates_Webserver@victorvox.net";

(Optional) hinzufügen normaler Updates

# vi /etc/apt/apt.conf.d/50unattended-upgrades-opt
              Unattended-Upgrade::Allowed-Origins {
                    "Ubuntu lucid-updates";
              };

# unattended-upgrades -d --dry-run
# unattended-upgrades -d
