I've been trying to make the package unattended-upgrades running under Debian GNU/Linux (7.0) with no success so far.

The steps I have followed:

  • Install unattended-upgrades
  • Enable it

    sudo dpkg-reconfigure -plow unattended-upgrades
  • Uncomment the following lines in /etc/apt/apt.conf.d/50unattended-upgrades

  • Wait two days

It's supposed to run every day, but it did nothing by the time. I've checked its logs at /var/log/unattended-upgrades/ and apt history log at /var/log/apt/history.log but nothing happened there since the installation.

Is there any step I am missing to enable it? After reading the doc under /usr/share/doc/unattended-upgrades/README, I think that the above are the only ones you have to follow to get it running.

    What is the value of APT::Periodic::Unattended-Upgrade (probably set in /etc/apt/apt.conf.d/10periodic)? – Steven Monday Mar 1 '13 at 13:59
  • In my case, it's set in /etc/apt/apt.conf.d/20auto-upgrades and its value is "1". – Fredrik Mar 1 '13 at 16:13

Try this:

Unattended-Upgrade::Origins-Pattern {

The file /etc/apt/apt.conf.d/20auto-upgrades must contain:

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