PMS won't start after upgrade to Ubuntu 24.04

[Treverr]

Got it! Will do-- annoyingly I JUST fresh-installed 22.04 a few weeks ago due to a totally unrelated problem. Guess I will do it again

[ChuckPa]

Extra Practice makes Extra Perfect

ps: I’m waiting on 26.04, or even 28.04 before moving from 22.04

[Treverr]

Oh you know one thing I just thought of though I don’t know if ti makes a difference.

My /var/lib/plexmediaserver symlinks into /mnt/plexdata because I put it on a SSD. Do you think that could cause an issue?

[ChuckPa]

Holy hell..

That’s important.

Stop the presses!!!

I’m willing to bet you don’t have /mnt/plexdata nounted with exec privilege. ???

Time to fix this the right way.

1. With PMS stopped
2. Remove the symlink
3. Recreate /var/lib/plexmediaserver and set owner plex:plex
   ( Required to have a real $HOME directory )
4. Create:
   – /etc/systemd/system/plexmediaserver.service.d/override.conf
5. Contents:

[Service]
Environment="PLEX_MEDIA_SERVER_APPLICATION_SUPPORT_DIR=/mnt/plexdata/Library/Application Support"

6. EDIT the /etc/fstab line for /mnt/plexdata . ADD ,exec option

---

Confirm the path above. Adjust as appropriate.

Customizing your Plex configuration on systemd based systems This information is intended for those systems where cat /proc/1/comm returns systemd. On systems which use Systemd (Ubuntu 16+, Fedora 26+, Centos 7+, Debian 8+,) you create this customization file which SystemD reads prior to launching PMS. This file is independent of the default configuration and service control mechanisms in /lib/systemd/system/plexmediaserver.service. Your customization override is preserved across updates, un…

I did all that but alas, same error upon reboot.

grab one last set of logs from “Logs”. Let’s see if any change.

What I’m reading is AppArmour being hostile. I’ve never seen it this way before.
There are a lot of folks using 24.04.

This is what I don’t understand.

When you reinstall 22.04, Install the DEFAULT (Minimal) Gnome desktop with the new /partition scheme (“something else” option)

@ChuckPa

AppArmour

For funsies I tried to disable app armor via GRUB_CMDLINE_LINUX="apparmor=0" and a reboot, still doesnt work

[ChuckPa]

it’s too interwoven into the whole thing. You can’t disable it.

[Treverr]

Womp. Well I am standing by to do your instructions if those Logs come back with nothing helpful either.

[ChuckPa]

what are all those containers you’re running.

What I’m finding now:

Start: 17:47:27.534
Aborted: 17:47:30.264

PMS has signal traps built in. This termination is so hostile, it can’t even exit cleanly.

It’s time

[Treverr]

Off we go! Appreciate the help none the less, I guess better it happens now before I get more stuff set up and have to redo more…

[Treverr]

Hours wasted but im back up on 22.04!

[ChuckPa]

All good and running?

Did you create /home partition?
Put APP SUPP Dir in /home/plex ?

For laughs, this is my PMS.

I am back in up and running yep!

Also I am 99% sure I figure out the issue, when I installed my Nvidia graphics driver, things stopped working again, downgraded and works fine. So I suspect 24.04 would have the same issue If I was brave enough to try and upgrade again, which im not.

[ChuckPa]

Oh? Which Nvidia driver did you install?

[Treverr]

`nvidia-driver-570’ from apt is what I installed originally, I believe

[ChuckPa]

Ahh, that explains it.

I have the RTX 2000 ada gen. I’m running the 565 drivers. (565.77)
With the P2200 , I run the 550 drivers. (550.120)

I would consider backing down off the 570 ledge. It’s new & somewhat Bleeding Edge.

[Treverr]

Yeah I think I just picked it because it was new… too bad I didnt figure that out before I reinstalled 22.04, oh well. You live and you learn.
