I tried to modify my fstab file and it doesn’t work.
My file is perfectly fine. But I cannot modify, I dont know why this happends. I try to open whit nano, but there is nothing inside. And the error “etc directory doesn’t exist”.
When I check in reading mode it shows up normally. And I try whit gedit but I don’t have the perms…
You probably didn’t supply the correct path to the file.
Writing to /etc/fstab requires root permissions. I’m not familiar with gedit, but any polkit-aware editor should normally prompt you for either the root password or the sudo password upon trying to save the file.
