Description kdebugs 2015-11-17 06:22:18 UTC 
I don't know how the software is put together, so if this belongs to another component or product, please reassign it, but both the fetching and the display is mediated via muon.

See also related Bug 295108, but it does not just affect PPA packages.  Also, it's not merely with 404 response codes;  the response code is often 200 OK even if the message says 404.  I will provide two examples below.

apport: 200 OK HTTP response with 404 in the HTML

    apport report is damaged, about a not installed package, or when an
    error occurred processing the report. (LP: #1512902)

Reproducible: Sometimes

Steps to Reproduce:
1. Click on a package
2. Click "Changes List"

It doesn't happen every time, but it happens with a fair number - for example just working through my list of installed packages in alphabetical order yielded these right off:
akonadi-server
apport
apport-symptoms
ark
baloo4
...
And this was the first few from not-installed packages:
account-plugin-icons
account-plugin-identica
account-plugin-mxit
account-plugin-sina
account-plugin-tools
account-plugin-zephyr
accountservice-ubuntu-touch-schemas
acpitail
...

Actual Results:  
If you click off and back on it, it might then immediately say:
  The list of changes is not yet available. Please use Launchpad instead.
But sometimes it tries multiple times to fetch the changes and ends up displaying garbage each time.

Expected Results:  
I don't care if it tries again or doesn't, but it should reliably display that "not ... available" message all the time rather than displaying unsanitized HTTP/HTML garbage.

Muon is no longer maintained, please switch no a supported alternative like https://apps.kde.org/discover/ or the package manager native no your system.

Sorry for the inconvenience.
