Hi guys !
I’ve got an issue with Plex on my quickbox server.
I’m using Ubuntu 16.04 LTS and QuickBox 2.5.4.
I wanted to update Plex but i didn’t see there was a commande (upgradePlex), so i have downloaded the .deb on the plex website to my server and run it with the command line : “dpkg -i plexmediaserver…deb”
All was ok but now plex don’t want to start, i’ve got a message when i launch “service plexmediaserver status” :
● plexmediaserver.service - Plex Media Server for Linux

Oct 02 15:34:15 quick systemd[1]: Failed to start Plex Media Server for Linux.
I don’t know what is the problem so i hope someone can help me to fix it.
I looked on google and don’t found a solution, i checked my system locale, checked all permissions and files and everything seems ok.
I restarted plexmediaserver several times and although made a hard reboot, just in case.
Do you have an idea ? (i prefer to not reinstall plex because i have a very huge music library with several playlists and don’t want to configure them again … 
)
Thanks a lot, have a nice evening
