I had issue with playsound package because "gi" was missing and I tried fallowing this and few others answers and broke ubuntu to the point it doesn't want to open temrinal.
I tried shift+alt+f3 but after typing credentials here i get message
/etc/update/motd.d/91-release/upgrade: /usr/bin/lsb/relase: /usr/bin/python3: bad interpreter: no such file or directory.
and when i try
sudo nano /usr/bin/gnome-terminal
it says
"sudo: nano: command not found" .
