[Bug 1851974] [NEW] changelogs not displayed

[arQon]

Public bug reported:

For the last few weeks, update-manager fails to show the changes for new
packages. Running it from a terminal, I see:

~ $  update-manager 
/usr/bin/update-manager:28: 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.
  from gi.repository import Gtk
/usr/lib/python3/dist-packages/UpdateManager/UnitySupport.py:29: PyGIWarning: Dbusmenu was imported without specifying a version first. Use gi.require_version('Dbusmenu', '0.4') before import to ensure that the right version gets loaded.
  from gi.repository import Dbusmenu, Unity
/usr/lib/python3/dist-packages/UpdateManager/UnitySupport.py:29: PyGIWarning: Unity was imported without specifying a version first. Use gi.require_version('Unity', '7.0') before import to ensure that the right version gets loaded.
  from gi.repository import Dbusmenu, Unity
Exception in thread Thread-1:
Traceback (most recent call last):
  File "/usr/lib/python3.5/threading.py", line 914, in _bootstrap_inner
    self.run()
  File "/usr/lib/python3.5/threading.py", line 862, in run
    self._target(*self._args, **self._kwargs)
  File "/usr/lib/python3/dist-packages/UpdateManager/Core/MyCache.py", line 320, in get_news_and_changelog
    self.get_changelog(name)
  File "/usr/lib/python3/dist-packages/UpdateManager/Core/MyCache.py", line 376, in get_changelog
    changelog = self._get_changelog_or_news(name, "changelog")
  File "/usr/lib/python3/dist-packages/UpdateManager/Core/MyCache.py", line 245, in _get_changelog_or_news
    "https locations with username/password are not"
UpdateManager.Core.MyCache.HttpsChangelogsUnsupportedError: https locations with username/password are notsupported to fetch changelogs

So, IDK exactly when the new version was pushed out, but that error's
nicely self-diagnosed at least: good job!  :)
