InnerException: System.IO.IOException: Permission denied

[luigiemby 0]

Im trying to add an usb drive and an internal one with different media files. I have change the permissions on the files and folders and im still getting the same error. The only way i can have movies is to add them in the /root/snap/emby-server folder.

Here is the error report

Any suggestions?

Hi @luigiembyplease attach the complete emby server log file. Thanks !

Hi @Luke. I have attached the log file. Any suggestions?

Did you mount ‘/media/username/Baal’ or did the desktop mount it automatically ? (if you don’t know it likely was the latter)

If so the OS will apply it’s default permissions (meaning the user logged into the will see the drive fine but others (ie. emby wont be able to see the drive)

You need to mount the drive differently, the most common way is in /etc/fstab.

Many of us here could walk you through this but I think A decent guide can explain this better:

https://pimylifeup.com/raspberry-pi-mount-usb-drive/

Ignore the RPi specific stuff @ the beginning and scroll down to the header:

    Mount a USB Drive to the Raspberry Pi Manually

 And get back if your still having problems

Hi @TMCsw. I did the whole procedure, but as soon as the drive mounts, ownership of the mnt folder goes to root. The files get mounted on the specified folder in the fstab file, but im still unable to see the files from emby.

I even created another folder, assign the ownership and saw that when it mounts, ownership shift again to root

That is normal and fine.

 Your getting closer, now you need to make sure the permissions are correct.

 Try using the following command ‘namei -mo /full/path/to/movie/movie.ext'

And post the results here (for example this is working fine on my system):

tmc@50:/mnt namei -mo /mnt/m/emby/OTA_movies/Armageddon\ \(1998\)/Armageddon\ \(1998\).mkv
f: /mnt/m/emby/OTA_movies/Armageddon (1998)/Armageddon (1998).mkv
 drwxr-xr-x root root  /
 drwxr-xr-x root root  mnt
 drwxrwxr-x emby emby  m
 drwxrwxr-x emby emby  emby
 drwxrwxr-x emby emby  OTA_movies
 drwxrwxr-x emby emby  Armageddon (1998)
 -rw-rw-r-- emby emby  Armageddon (1998).mkv

Note that emby needs permissions thought the chain of directories (minimum rx for emby/others) and r for the actual file.

Here the results of the command. Thank you for your help @TMCsw

Are we getting closer?

namei -mo /mnt/media/Peliculas/50\ 50/50.50.2011.DVDScr.XviD-playXD.avi
f: /mnt/media/Peliculas/50 50/50.50.2011.DVDScr.XviD-playXD.avi
 drwxr-xr-x root root /
 drwxr-xr-x root root mnt
 drwxrwxrwx root root media
 drwxrwxrwx root root Peliculas
 drwxrwxrwx root root 50 50
 -rwxrwxrwx root root 50.50.2011.DVDScr.XviD-playXD.avi

[TMCsw 156]

Sorry was busy, but I think that should be working ? (although a little too open)

Lets’ try this command: (it lets emby own it)

sudo chown -Rv emby:emby /mnt/media/Peliculas

So the other things that could be wrong:

•   Something is restricting access in /etc/fstab please post it here
•   Your using the Snap version , perhaps they need the disk passed through (I don’t use snaps so I don’t know)
•   Some times you need to type in (or cutNpaste) the folder (in emby) instead of using the picker.    
•   Also you appear to be running an old version of Ubuntu with newer kernel

We probably need more info to help 

@Q-Droidam I missing something?

My guess is that snap sandboxing could be at play here and why it works when media is in the snap path. Chances are that it's not running as emby, might not even have an emby user on the host and I don't know what the runtime user actually is for emby snaps. Sorry, I don't have much to offer on this one.

@Q-Droidyou are right about the user. There is no emby user on the passwd file.

I've asked our build developer to come in here and comment on this. Thanks guys.

[alucryd 231]

This is indeed a result of snap's sandboxing. By default the snap runs as root, but can't access anything. We rely on the `removable-media` plug instead [0], but even this one does not auto-connect (forget the `home` and `system-files` plugs, our snap was rejected when we had them activated). To connect the `removable-media` plug, please run `sudo snap connect emby-server:removable-media :removable-media`. Then you should have access to anything under `/media`, `/run/media` and `/mnt`.
