Couthpotato no longer starting

Question

Running CouchPotato on a Synology NAS, and I believe CouchPotato recently tried to auto-update itself, because it suddenly stopped working. I tried the solution recommended here, but that doesn't work. Judging from the logs, it looks like some SQL update is trying to run but it returns an error:

OperationalError: (OperationalError) duplicate column name: last_edit '\nALTER TABLE release ADD last_edit INTEGER' ()

The last line seems to be the key, ie. the error "duplicate column name: last_edit '\nALTER TABLE release ADD last_edit INTEGER' ()".

Any thoughts on how to fix this?

Answer 1

The final solution I ended up with was to uninstall it, then install custom CouchPotato package specifying the RuudBurger repo as described here. If you don't use the RuudBurger repo, then you get the french CouchPotato.
