How do you connect to your Plex database to see the schema using DB Browser for SQL Lite?

Hello,

I'm trying to use DB Browser for SQL Lite to connect to the Plex database stored on my Ubuntu box. Everytime I use this SQL client to open the database, I get an "Invalid file format" error. The database is located under /var/lib/plexmediaserver/Library/Application Support/Plex Media Server/Plug-in Support/Databases/com.plexapp.plugins.library.db.

I thought it might be a permission related issue so I ran chmod 755 on the above file as well as the db-shm and db-wal files.

I still can't connect. Does anyone have any suggestions?

Thank you,
Jason
