Something is going wrong with updating one of the databases. The Epg11.db file may be corrupted.

Yep I spotted that too 
So, what do I need to do? Should I delete that Epg11.db file? Where is it stored?
I used a shared MYSQL database, will this Epg11 data be being stored on there?
No, only the video and music databases will be on your MySQL server, as you can see yourself using a MySQL client.
"epg11.db" is part of the database files that are always stored on the Kodi client itself, something the Kodi devs have decided in their infinite wisdom. You can the local databases in /storage/.kodi/userdata/Database . Normally after deleting a local database file, it will be recreated after a reboot/restart of Kodi. What it means for the workings in your setup(s) I don't know, as I never use any Live TV or EPGs in my Kodi clients.
