Description:
DVB-T scan data downloads fail in Kaffeine. The issue has been ongoing for at least 2 years now. However, DVB-T frequencies change so slowly that it takes a long time to actually cause problems, up until ~now. ;-)

This Ubuntu bug report contains further context (on the DVB scan file naming changes): https://bugs.launchpad.net/ubuntu/+source/kaffeine/+bug/1879923
It also links to a patch that should fix the problem: https://launchpadlibrarian.net/553671878/kaffeine_2.0.18-1ubuntu1.debdiff
Here's the file name currently available for download: https://autoconfig.kde.org/kaffeine/
Here's a long mail thread with even more details: https://www.spinics.net/lists/linux-media/msg55299.html

Additional info:
* package version(s) — kaffeine 2.0.18-2
* config and/or log files etc. — N/A
