[Łukasz Zemczak]

Hello Brian, or anyone else affected,

Accepted ubuntu-release-upgrader into hirsute-proposed. The package will
build now and be available at
https://launchpad.net/ubuntu/+source/ubuntu-release-upgrader/1:21.04.16
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how
to enable and use -proposed.  Your feedback will aid us getting this
update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, what testing has been
performed on the package and change the tag from verification-needed-
hirsute to verification-done-hirsute. If it does not fix the bug for
you, please add a comment stating that, and change the tag to
verification-failed-hirsute. In either case, without details of your
testing we will not be able to proceed.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance for helping!

N.B. The updated package will be released to -updates after the bug(s)

Title:
  check-new-release-gtk crashed with ValueError in require_version():
  Namespace Gtk is already loaded with version 4.0

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

Bug description:
  Impact
  ------
  check-new-release-gtk is crashing on Ubuntu 21.04 if gir1.2-gtk-4.0 is installed on the system and based off the number of crashes at the Ubuntu Error Tracker that seems to be a rather popular package. The crash would prevent users from being notified about Ubuntu 21.10 when it becomes available.

  Test Case
  ---------
  On an Ubuntu 21.04 system
  1) sudo apt-get install gir1.2-gtk-4.0
  2) Run /usr/lib/ubuntu-release-upgrader/check-new-release-gtk

  Observe a Traceback with the contents

  "check-new-release-gtk crashed with ValueError in require_version(): Namespace Gtk is already loaded with version 4.0"
  or
  "AttributeError(\"%r object has no attribute %r\" % (\nAttributeError: ''gi.repository.Gtk'' object has no attribute ''Container''"

  Where Problems May Occur
  ------------------------
  check-new-release-gtk could crash entirely if the additional code is incorrectly written (i.e. there's a syntax error) however the test case does cover that.
