Today I installed gnome-shell via terminal #apt install gnome-shell and tried to reboot my computer, but Ubuntu did not start.
It stays in the loading screen forever and it won't let me ctrl+alt+F2 to enter TTY2.
I don't know how to fix it, neither I know how to uninstall gnome-shell.
There are similar questions about this problem, which looks like they have not actual solution, the questioner know beforehand how to uninstall gnome in this situation.
