When the system boots, it displays the "Oh no! Something has gone wrong." error message. I have no idea how to fix this since I'm not able to access the TTY (Ctrl + Alt + F1 or F2 not working). When I press the keys for the TTY shortcut, it only displays ^[[[A for a few seconds after returning to the error screen.
You could type “e” at the grub menu, to be able to edit the grub commandline
and add a “3” (without the quotes) to the end
then boot - it will boot to TTY without trying to start the graphical session
(also called runlevel 3)
