Why I'm unable to write on USB via Files (Nautilus, graphic UI) and I'm able to write on it using CLI?
Using Files I'm getting the error: Error while copying to "DEVICENAME". This destination is read-only.
Using CLI I'm able to create new files, copy content and so on.
Here is the output of mount for the related device:
/dev/sdb2 on /media/USERNAME/DEVICENAME type fat (rw,nosuid,nodev,uid=1815567,gid=333,shortname=mixed,dmask=0077,utf8=1,showexec,flush,uhelper=udisks2)
I don't have root permission.
