I can install it but it can't see my files. I believe It's a permission issue because plexmediaserver is run by 'plex' user. In Ubuntu 14.04, I could edit /etc/default/plexmediaserver so that it would be run by me. It's doesn't seem to work in 16.04 (because systemd ?).
I've tried http://www.htpcguides.com/install-plex-media-server-ubuntu-16-x-and-later/, with the debian source or with the deb. I can't seem to start the service ..
[user@machine]:[~] $ sudo systemctl start plexmediaserver.service
Job for plexmediaserver.service failed because the control process exited with error code. See "systemctl status plexmediaserver.service" and "journalctl -xe" for details.
