[Bug 2068809] [NEW] changelogs not listed for PPA packages

[Tormod Volden]

Public bug reported:

When clicking on a package from a PPA in update-manager, the "Changes
for XXX versions:" section will say:

"This update does not come from a source that supports changelogs."

and on the console it dumps:

ERROR:root:Unable to find a valid PPA candidate URL.


The reason is that in _extract_ppa_changelog_uri() in /usr/lib/python3/dist-packages/UpdateManager/Core/MyCache.py it checks only for ppa.launchpad.net but nowadays the URI will contain ppa.launchpadcontent.net instead.


With the below patch it will correctly display the changelogs:
