check-new-release-gtk exits with PyGIWarning:GTK

[Bill (franksmcb)]

Ubuntu MATE 19.04.

Try to upgrade to release 19.10.

Expected Result:
run Alt+F2 then check-new-release-gtk
GUI option to upgrade should be presented

Actual Result:
Alt+F2 window closes and nothing occurs.

Run this command in the terminal and the following is generated:
/usr/lib/ubuntu-release-upgrader/check-new-release-gtk:30: PyGIWarning: Gtk was imported without specifying a version first. Use gi.require_version('Gtk', '3.0') before import to ensure that the right version gets loaded.

This is working using Ubuntu MATE 18.04 and upgrading to Ubuntu MATE 20.04

However I do get this error message in the terminal:

[Brian Murray (brian-murray)]

check-new-release-gtk didn't exit because of the PyGIWarning rather it was because of a failure to get the meta-release information from changelogs.ubuntu.com. However, because this warning message is confusing I'll go ahead and fix this and use this bug for that issue.

[Launchpad Janitor (janitor)]

This bug was fixed in the package ubuntu-release-upgrader - 1:20.04.17

---------------
ubuntu-release-upgrader (1:20.04.17) focal; urgency=medium

  * DistUpgrade/DistUpgradeFetcher.py,
    DistUpgrade/ReleaseNotesViewerWebkit.py: use gi.require_version so that
    the right version gets loaded and warning messages are not displayed.
