Title:
  lock screen message appeared during an SSH upgrade

Status in ubuntu-release-upgrader package in Ubuntu:
  New

Bug description:
  I was upgrading and Ubuntu 20.04 system to Ubuntu 22.04 over an ssh
  connection and noticed the following message:

  `Unable to disable lock screen

  It is highly recommended that the lock screen be disabled during the
  upgrade to prevent later issues. Please ensure your screen lock is
  disabled before continuing.

  To continue please press [ENTER]`

  Given that I'm connected via ssh the message seems unnecessary. Some
  details from main.log:
