Expected results:
Muon is able to show changelog for packages.

Actual results:
Muon is unable to show changelog for packages.

Notes:
1. `apt-get changelog samba cups` returns changelog from http://changelogs.ubuntu.com as expected.
2. It seems that Muon was incorectly setup after importing from Debian.
