I need to check what has been installed on remote Ubuntu server by package security channels.

How could I do that in bash?

For manually installed I could check:

  • /var/log/dpkg.log
  • /var/log/apt/history.log

The package unattended-upgrades install software automatically (Default: only security updates). You can find the logs in:


The official documentation: Automatic Updates

You can custom the Automatic security Updates
