ModuleNotFoundError: No module named '_sqlite3'.

next time, i will read the comments before reading the post :D because i just destroyed my distribution

as said above, command sudo apt install --reinstall ubuntu-desktop fixes the problem. But you need an automatic Internet connection, as it can be difficult to set up through the console

That lone command will not restore everything that was removed. It will only restore ubuntu-desktop and its dependencies! You'll need to make an install script out of everything that got removed.

For example on my machine I'd have to run the following. It will be different for everyone, because it depends what you had installed.

When you are uninstalling python3 it will tell you every package that will also be removed. That's how you build your reinstall script - just copy everything into a single line, then add sudo apt install in front.

Of course this is after you reinstall python.

OMG you are a mfcker. I got my VM almost completely destroyed but i got to recover it. You are a piece of crap.

OK ... NOT ALL OF YOU KNOW THIS...
