Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free.

I just installed the Plex media server from the Ubuntu Software Center, and opened the web interface. I wanted to start by adding a collection. When it gave me a file browser, I wanted to go to /home/robin/Videos. /home is as far as I got. It showed robin, with an arrow in front of it, but when I tried to expand the directory tree it was empty. The same happened when trying to access /media/Data. For me it's quite useless like this, as all of my media files are inside those 2 directories.

Help would be much appreciated.

My first guess seemed to be a correct one; It is, as always, a permissions problem. How do I give plex access to my home folder without also giving other users access to it? My home folder is encrypted by the way, so that'll probably complicate things a little.

robin@RobinJ:~$ sudo -u plex bash
[sudo] password for robin: 
bash: /home/robin/.bashrc: Permission denied
plex@RobinJ:~$ ls -al
ls: cannot open directory .: Permission denied
plex@RobinJ:~$ cd /home
plex@RobinJ:/home$ cd robin
bash: cd: robin: Permission denied
plex@RobinJ:/home$ ls -al robin
ls: cannot open directory robin: Permission denied

You've got two options I think. You can run plex media server as your user, or you can add yourself and plex to a group and give that group access to your home folder. I run Plex Media Server on OS X for the time being, so I haven't run into this problem myself, but the fix should be fairly trivial. This link explains how to add users to groups in linux, that's the way I think I'll be going when I switch my Plex server to Ubuntu.

Yeah, running it as the current user does indeed solve this particular problem. –  RobinJ Jun 15 '12 at 9:15
    
But why plex can't access files. Files in home folder are readable by any user. –  umpirsky Sep 20 '12 at 18:37
    
What is strange is when I do sudo -u plex bash I can list home folder as plex user, but from plex app, it logs Error listing directory [/home/umpirsky] - boost::filesystem::status: Permission denied. How is that possible? –  umpirsky Sep 20 '12 at 19:11
    
@umpirsky This confused me too, but eventually I learned that Plex requires write permissions on the file before it will detect it. –  machineghost Jun 14 '13 at 3:09

Add plex as a user in your group , then add root as a user in your group .

then type sudo gpasswd -a root yourusernamehere,sudo gpasswd -a plex yourusernamehere you will have to give sudo password which is your password and then run this command using your drive path , mine is /media/PLEX for my external drive input your path here where u see /media/PLEX

find /media/PLEX -type d -exec chmod 755 {} \;; find /media/PLEX -type f -exec chmod 644 {} \;

This will ultimately allow plex to use your files & folders. Hope this helps.

Why does one have to add root to the usergroup? –  erb Jun 11 '14 at 13:41
  1. Install Plex.
  2. Open terminal.
  3. Install samba - sudo apt-get install samba.
  4. From ~ do cd ... This will take you to /home.
  5. Create new plex folder in /home: sudo mkdir plex
  6. Go to new folder: cd plex
  7. Create new folder in plex/: sudo mkdir music
  8. Set permissions: sudo chmod 777 * -R
  9. Set owner if required sudo chown plex:plex -R

Do the same for other media if required, don't forget if you add new media you may need to set permissions/owner on that too.

Are you sure you have the right syntax for the chown command? –  Eliah Kagan Jul 9 '12 at 2:13

Try adding Plex to the plugdev group.

Open a terminal (Press ControlAltT) and enter

sudo gpasswd -a plex plugdev

Verify that plex was added to the plugdev group by entering:

groups plex

which should display what groups plex belongs too. Next, reboot the computer and start plex to verify this corrected the problem.

If just adding plex to plugdev works for you, then you are much better off than adding plex to your usergroup as suggested in other answers. That may work but it's not a great idea security wise.

Why is a restart necessary? (I haven't verified if you solution works because I don't have the privilege to be able to restart my server without considerable work) –  erb Jun 11 '14 at 13:40

Plex is run under "plex" user, so you may encounter the following permissions issues:

  • Ubuntu restricts access to /media/$USER through ACL (that's the "+" when you ls -l /media). See below for solution.
  • Your drives may not be mounted to allow plex user to read it. Check it with ls -l on the drive or folder that cause issue, to see the group owner, group permissions and user permissions. See below for solution.
  • Your folder may not allow plex user or group to read it. Use sudo chmod -R u+r FOLDER to allow all users. Or add flex user to the folder group (see below) and use sudo chmod -R g+r FOLDER.

Allow Plex to access /media/$USER:

Check which group you and plex belong to:

groups
groups plex

Allow plex user to access /media/$USER (replace MYGROUP by your user group). In this case, we add plex to your user group, and allow this group to access /media/$USER:

sudo usermod -a -G MYGROUP plex
sudo chown MYGROUP:MYGROUP /media/$USER
sudo chmod 750 /media/$USER
sudo setfacl -m g:MYGROUP:rwx /media/$USER

For NTFS partitions, you need to mount it with read rights in /etc/fstab:

Check your user and group id (1000 and 1000 in example):

id

Edit /etc/fstab to mount the drive with read permissions for the user group and for all users (cf. umask, which is 777 less the desired "chmod" number):

UUID="XXXXXX" /media/USERNAME/MOUNTPOINT ntfs rw,nosuid,nodev,allow_other,default_permissions,uid=1000,gid=1000,umask=002 0 0

Note: If you're using mdadm, this may be needed in /etc/mdadm/mdadm.conf:

CREATE mode=0775
