To activate unattended-upgrades, you need to ensure that the apt configuration stub /etc/apt/apt.conf.d/20auto-upgrades contains at least the following lines:

• # editor /etc/apt/apt.conf.d/20auto-upgrades

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

  dpkg-reconfigure -plow unattended-upgrades

Alternatively, you can also create the apt configuration file /etc/apt/apt.conf.d/02periodic to activate unattended-upgrades:

• # nano /etc/apt/apt.conf.d/02periodic
  
  

   

  Below is an example /etc/apt/apt.conf.d/02periodic:

  • // Control parameters for cron jobs by /etc/cron.daily/apt-compat //
    
    
    // Enable the update/upgrade script (0=disable)
    APT::Periodic::Enable "1";
    
    
    // Do "apt-get update" automatically every n-days (0=disable)
    APT::Periodic::Update-Package-Lists "1";
    
    
    // Do "apt-get upgrade --download-only" every n-days (0=disable)
    APT::Periodic::Download-Upgradeable-Packages "1";
    
    
    // Run the "unattended-upgrade" security upgrade script
    // every n-days (0=disabled)
    // Requires the package "unattended-upgrades" and will write
    // a log in /var/log/unattended-upgrades
    APT::Periodic::Unattended-Upgrade "1";
    
    
    // Do "apt-get autoclean" every n-days (0=disable)
    APT::Periodic::AutocleanInterval "21";
    
    
    // Send report mail to root
    //     0:  no report             (or null string)
    //     1:  progress report       (actually any string)
    //     2:  + command outputs     (remove -qq, remove 2>/dev/null, add -d)
    //     3:  + trace on
    APT::Periodic::Verbose "2";
