Hey, looks like something related to MythTV PVR functionality broke. I’m not exactly sure when, but this is what I’m getting:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created

The following information may help to resolve the situation:
The following packages have unmet dependencies:
kodi-pvr-mythtv : Depends: kodi-api-pvr (= 5.2.1)
E: Unable to correct problems, you have held broken packages.
Just for kicks, I tried getting kodi-api-pvr but doing that apt wanted to remove osmc so … that’s a no-go 
Can you fix your repos so I can play back LiveTV again pretty please?
