changelogs not listed for PPA packages

[Tormod Volden]

* Impact

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."

Which seems a side effect of https://blog.launchpad.net/ppa/new-domain-names-for-ppas , the code filter on ppa.launchpad.net in the url where those are using ppa.launchpadcontent.net now

* Test case

- enable a ppa including an update for a package you have installed
- start update-manager and select that package
- check the long description at the bottom

it should display the changelog entry for the update

* Regression potential

The change is in the _extract_ppa_changelog_uri() function so a potential issue would impact updates coming from a ppa. Verify that those are correctly listed and include a valid description

-----------------------------------------------

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:

Thanks, I've uploaded the fix to Oracular.

There is another upload pending already in the Noble queue but the fix makes sense for a next upload.
Would you perhaps have some time to help with that and make the bug description SRU compliant (https://wiki.ubuntu.com/StableReleaseUpdates#SRU_Bug_Template)?

In a 24.04 virtual machine I installed update-manager/1:24.04.8. I did

  apt-add-repository ppa:nteodosio/rebuilds

and started update-manager. It correctly showed the "Software Updater" in the list with the change log saying

--->
Technical description
[--snip--]

Changes for update-manager versions:
Installed version: 1:24.04.8
Available version: 5:74.04.2

Version 5:74.04.2:

  * foobar
<---

which is correct.
