I modified /etc/fstab
to change permissions over a mounted disk in Ubuntu 16.04, and now I can't start Ubuntu. First, it shows some messages, and then it starts showing this error until I shut it down (I've tried to press Ctrl+C, Crtl+Alt+F2, Ctrl+Alt+all other Fs, and many other combinations, but it won't stop showing that error).
I think this problem would be solved if only I could modify back fstab, but I can't find a way to do it. I have found a solution to login in text-only console mode by pressing "e" in GRUB and adding pcie_aspm=off
at the end of the Linux line. This allows me to start Ubuntu in a non-graphic mode without showing the error, and login with my user and password, but when I try to modify fstab it says that the system is in an read-only mode and that I can't modify the file.
Do you have any idea of how can I login some way that allows me to modify that file?
If it helps here is an image of the modification I made to the fstab file. The only thing I added is what is underlined in red.
