Plex Service Crashes on Start-Up after Update

Plex Media Server Desktops & Laptops
1

Server Version#: 1.26.0.5715
Player Version#:

As with many other users, after an update, the plex service crashes after being (re-)started. DB appears to be corrupted and I’ve attempted to repair it [ LINK ] (see below), but it still crashes after restart. Note that you can access it locally (for about 3 seconds before it stops responding and refreshing the page (x.x.x.x:32400/web/index.html#!) results in Connection Refused.

What would my next attempt be? Am I in a wipe Plex/re-install territory now?

Next step is to try the Repair a Database link mentioned above…

  1. Stop Plex Service
sudo systemctl stop plexmediaserver
  1. Back Up DB
cd "/var/lib/plex/Plex Media Server/Plug-in Support/Databases"
cp com.plexapp.plugins.library.db com.plexapp.plugins.library.db.original
  1. Check for Corruption
 -- "/usr/lib/plexmediaserver/Plex SQLite" com.plexapp.plugins.library.db "PRAGMA integrity_check"

This resulted in a page of Row X missing from index and wrong # of entries in index etc…

  1. Attempt to repair DB
"/usr/lib/plexmediaserver/Plex SQLite" com.plexapp.plugins.library.db ".output recover.out" ".recover"

This takes all of 15 seconds, for a large file full of DB (Re-)Creation Syntax.

Restart Service and check x.x.x.x:32400/web/index.html#!/. It loads, but with no library. I try to refresh the page 30 seconds later and it returns to Connection Refused and the service has crashed.

There are no files in the mentioned crash location…

Try the Manually Repair the Database process as well.

No need to completely remove/re-install.

If repair or restore from backup fail, then delete the database.

From the repair document: Note : You can also simply delete the com.plexapp.plugins.library.db database file while the Plex Media Server is not running. Restarting the server will then restore your server to a nearly-fresh install state. (i.e. You will lose your existing libraries and need to recreate them , but you won’t be affecting your content itself.).

Thanks. I was getting ready to write the DBs obituary, when I realised the new DB was owned by root. We’re all up and running now (for now).

4: Attempt to manually repair DB

cd "/var/lib/plex/Plex Media Server/Plug-in Support/Databases"
"/usr/lib/plexmediaserver/Plex SQLite" com.plexapp.plugins.library.db ".output dump.sql" ".dump"

sudo rm com.plexapp.plugins.library.db

"/usr/lib/plexmediaserver/Plex SQLite" com.plexapp.plugins.library.db ".read dump.sql"

FAILED - Plex Service won’t even start

Reset DB’s Permissions

sudo chown -Rf plex:plex com.plexapp.plugins.library.db

Hey presto…
