Hello,
I have a network share mounted through cifs on fstab and most of the snaps I install are not able to write on these mounts… Is there any way to override this setting without losing all confinement? Well if I have to lose it I guess that’s fine too…
Cheers
Hello
Can you please give us more information about the setup you have. I believe that the line describing cifs would be sufficient. I will try to add support for this use case for snapd 2.39 if possible.
For example, I install subliminal-subtitles
snap install subliminal-subtitles
I have my fstab like this:
//192.168.1.***/Public /media/nas-public cifs _netdev,uid=*****,gid=*****,iocharset=utf8,file_mode=0660,dir_mode=0770,username=*****,password=***** 0 0
When I try something like:
subliminal-subtitles download -v --language pt some-movie.mkv
I get the error

This kind of error happens to almost any snap that tries to write on a remotely mounted share.
do you have the removable-media interface of sublimal-subtitles connected ?
sudo snap connect subliminal-subtitles:removable-media
if your user normally has permissions to write to /media/nas-public and the interface is connected, the app should theoretically work. from a toplevel view it should really not make a difference if the /media/nas-public dir is using a network filesystem or is a locally mounted filesystem as long as the above is true.
Hello @brunorene,
I have the same problem here.
Snap is installed.
I installed cloudcompare and visualsfm.
My homedir is mounted to a CIFS share on the network.
I have the same error in the two applications:
Cannont create user data directory /mount-point/myaccount/snap Read-Only file system
Even if I can create a directory if i use the command:
mkdir /mount-point/myaccount/snap/myapplication/test with no error.
If i create a local user with a local directory i can open the application
home dirs are completely different from removable devices (from a snap POV at least), here is a bug about it:
