I'm working on an old HP tower that seems to not like any of the updates being pushed by Ubuntu. So I am still running 16.04. A recent update broke my entire system and I had to reinstall my OS. Since doing that I have not been able to find how I set the permissions for plex to be able to see my media folders.

They are currently split between two drives at the following locations /SharedSpace/Videos & /MyBook/Videos. This all worked last week and now I can't seem to find instructions that allow plex to access those folders to populate the library.

I also can not find where how to move the plexMD folder from the home directory to a partition that has more space.

Any help would be greatly appreciated.

Here is the output of my df -h command

    Are your files for Plex on external drives? – Terrance May 23 '19 at 22:25
  • /MyBook is external and /SharedSpace is a partition on an internal drive. – JohnTErskine May 23 '19 at 22:27
  • These are their entries in /etc/fstab # /SharedSpace was on /dev/sda4 during installation UUID=A545-4CD0 /SharedSpace vfat utf8,umask=007,gid=46 0 1 /dev/disk/by-id/usb-WD_My_Book_1140_574343315430313532313934-0:0-part1 /MyBook auto nosuid,nodev,nofail,x-gvfs-show,x-gvfs-name=MyBook 0 0 – JohnTErskine May 23 '19 at 22:30
  • I edited the main post and I don't recall exactly how I installed plex. I know i used the Ubuntu Software app and then I did some work through the terminal. I can see the plex server running through my browser, but I can not navigate to the desired folders to add libraries. – JohnTErskine May 23 '19 at 22:40
  • I am fine if i need to purge and reinstall. Is there a preferred way to do that? – JohnTErskine May 23 '19 at 23:02

Unfortunately, the snap version of Plex Media Server can have the problem of not being able to read into other folders on the drive due to containment of the application. To solve this, first remove the snap version of Plex

sudo snap remove plexmediaserver

Following this link here add the Plex repository to your system

echo deb https://downloads.plex.tv/repo/deb public main | sudo tee /etc/apt/sources.list.d/plexmediaserver.list

Add the key

curl https://downloads.plex.tv/plex-keys/PlexSign.key | sudo apt-key add -

Update the system and install Plex Media Server

sudo apt update
sudo apt install plexmediaserver

If it complains that it is already installed, it would be best to reinstall it

sudo apt install --reinstall plexmediaserver

Run Plex normally. The following link can help with moving the metadata to another location for safe keeping.


Hope this helps!
