Server Version#: 1.43.0.10492
Player Version#: N/A

Linux Mint 21.1 Vera x86_64
Kernel 5.15.0-171

Updated to Plex Server 1.43.0.10492 using downloaded .deb file. No start on the service with immediate core dump on every attempt. Attempted to revert back to 1.42, but still core dumped every start. No core dump available to provide unfortunately, I had to restore from backup to get back up and running.

I’m pretty sure Mint is not a Plex supported platform.

It’s built on Ubuntu, just a different GUI. That shouldn’t cause any issues with the 1.43.0 update.

Mint is not supported.

Saying it’s built on Ubuntu doesn’t cut it. I can’t tell you how many have tried.
I’ve spent hours debugging Mint without success hence why it’s not supported
Once they go to Ubuntu or Debian, all is well .

Well it ran fine for 3 years until this version. No time currently to rebuild right now. Going to have to wait.

Do you have your server logs ?

maybe there’s something in there.

Please provide ALL the info you can so we can help.

you might have a damaged DB – which can be resolved

try tossing it into a docker, sometimes buffers against OS compatibilities: https://hub.docker.com/r/plexinc/pms-docker/

I’ll take another backup this weekend and try a few things. If it goes sideways again I’ll remember to pull the core dump down before I restore.

EDIT: Instead of pulling log files, download and run DBRepair for Plex Media Server.

It will check for database structural problems and attempt to correct any it finds. It will also optimize the database in the process.

# Download latest version. 
# This overwrites any existing version.  Remove "-O DBRepair.sh" to not overwrite.
wget -O DBRepair.sh https://github.com/ChuckPa/PlexDBRepair/releases/latest/download/DBRepair.sh

# Make it executable
chmod a+x DBRepair.sh

# Run it as root.
sudo ./DBRepair.sh

Use AUTO to check for problems and optimize the database.

If the process is successful, then START and EXIT.

If DBRepair finds problems it cannot correct, use REPLACE to check for viable backup versions of the database.

If it cannot repair the problems and cannot find a viable backup, then report back and include the output of the tool. Use SHOW to print the contents of the log file to the screen.


The Plex server log files are needed to check for database corruption or other problems.

The existing files may provide useful information. If possible, pull them and upload to the thread.

$ cd /var/lib/plexmediaserver/Library/Application\ Support/Plex\ Media\ Server/
$ sudo tar czf logs.tar.gz Logs

DBRepair found errors in the fts4_metadata_titles and fts4_metadata_titles_icu and was able to repair them. Subsequent update to 1.43 was successful. I’ll keep and eye on it the next few days. Thanks for the help. I’ll plan on moving it to a Ubuntu install in the future.
