Plex Media Scanner crashes when trying to list (-l)

Plex Media Server Desktops & Laptops

I was going to update a library via the terminal but didn’t know the library Id, so I ran

Plex Media Scanner -l

But it just spits out some strange data and then crashes…

I’ve been testing this the during the latest three updates, but it’s still the same…

Looks like you might have some corruption in your database. https://support.plex.tv/articles/201100678-repair-a-corrupt-database/

Edit - It could also be your PMS hasn’t run through a proper migration to update the database to the latest scheme. Restart PMS, let it run without doing anything for 3 minutes, get me the log and I can check if it completed.

A few questions:

  1. Is the EUID / EGID those of the Plex user (plex:plex) ?
  2. Are the environment variables set?

I ask this because the tool is UID/GID sensitive

That’s been done several times, I have however fixed the issue.

A few directories was the property of root (fixed that) the $PLEX_HOME wasn’t set…
… But in think I solved it anyway, it was a DBK issue (Dumbass Behind Keyboard). I was always running the command as my user, I never ran it as Plex.

But since I can’t login on the plex account, I must go via sudo su | su Plex .
Isn’t the commands suppose to be executed by my default user?
