Thank you

Thank you, these steps were really helpful for me too.

But a word of caution for Ubuntu 22-04, (I'm not sure if it applies to new Ubuntu versions): changing the default python3 version breaks the terminal app. (See https://askubuntu.com/questions/1442350/terminal-not-launching-in-ubuntu-22-04 for a discussion)

To avoid that, make sure that the existing python3 version has the highest priority, e.g.

sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.10 2
sudo update-alternatives --install /usr/bin/python3 python3 /usr/bin/python3.11 1

very helpful

thanks!
