I just upgraded from Ubuntu 21.10 to Ubuntu 22.04. Everything perfect except for python. Python 3.11 or 3.10 broke my python scripts. In my struggle I think i damaged the system and now I have mess: I seem to have all 3.9, 3.10, 3.11 and cannot open a terminal etc... Can you please help? Many thanks for reading. Best regards, Zuheyr

    If you "damaged the system", then reinstall Ubuntu to undo the damage. DON'T change the version of Python3 included with Ubuntu -- that will break your system. To run a different version of Python is fairly easy to do if you avoid the mistake of trying to install it through apt. – user535733 Apr 25 '22 at 15:38
  • tried apt related command - `apt autoremove'? Also try doing a update one more time as in `sudo apt-get update && sudo apt-get upgrade && sudo apt autoremove' So system automatically update, upgrade & remove all packages as needed – Aravinth Apr 25 '22 at 15:59
  • Also, as you mentioned 'I think i damaged the system', Check your terminal command run & apt history -As it has all the history of previous runs, Its easy to find out where exactly you broke it (f you could find that, can easily revert) – Aravinth Apr 25 '22 at 16:03

    Please reinstall. Messing with the default python is a fatal mistake. Almost the whole desktop is driven by python. – vanadium Apr 25 '22 at 16:46

    Does this answer your question? [Removed Python 3 and now Ubuntu Software Center, terminal and other applications don't work](https://askubuntu.com/questions/384033/removed-python-3-and-now-ubuntu-software-center-terminal-and-other-applications) – karel Jun 20 '22 at 03:03

Run

sudo apt install ubuntu-desktop

and you will get your system back.

I have the same issue, I cannot install Python 3.6. Ubuntu 2022 comes with Python 3.10.

If you have scripts that require an older version of Python and/or certain versions for specific modules and there are no packages to remedy this, your best bet—at least as a temporary workaround—is to ensure that said scripts work in a separate environment. One possible building block which I use myself is pyenv (Simple Python version management).
