Database Repair Error: no such collation sequence: icu_root

If the image is malformed (corrupt), you’ll need to use one of the backup databases

  1. Move this ‘current’ one off to the side.
  2. Copy the most recent backup (look at the dates)
  3. Name it com.plexapp.plugins.library.db
  4. Be certain to make sure UID/GID is correct

Future reference, You can type:

"/usr/lib/plexmediaserver/Plex Media Server" --sqlite com.plexapp.plugins.library.db

and you’ll stay on the sqlite command line.
