Hello Brian, or anyone else affected,

in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See

update out to other Ubuntu users.

mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
jammy to verification-done-jammy. If it does not fix the bug for you,
please add a comment stating that, and change the tag to verification-

not be able to proceed.

Title:
  lock screen message appeared during an SSH upgrade

Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in ubuntu-release-upgrader source package in Jammy:
  Fix Committed

Bug description:
  [Impact]

  Server users will see an unnecessary error message about failing to
  disable the lock screen, which may cause confusion.

  [Test Plan]

  * Obtain a console on Impish server, e.g. ssh to a remote host.
  * Verify that XDG_SESSION_TYPE is set to 'tty':
    
    $ echo $XDG_SESSION_TYPE

  * Start a release upgrade:

    $ do-release-upgrade

  * After accepting the prompt to start the upgrade, observe the "Unable
  to disable lock screen" message.

  [Where problems could occur]

  The patch changes the early-return condition in the except block in
  _inhibitIdle. If problems occurred, it would be related to the "Unable
  to disable lock screen" message.

  [Original 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:
