the dependency is there -- it must've been whatever you did: https://github.com/deadsnakes/python3.9/blob/ec8b7b6b6aa5b197eb20e9cea7e1283541ae088d/debian/control#L209

using sudo to delete system package managed files is a very bad idea, why did you do that?

you can probably fix with sudo apt install --reinstall python3-distutils -- but this has nothing to do with deadsnakes so I can't help you further with free support

that solved it, guess i should reinstall all python3-* packages?

i assumed since my system only ships with python 3.8, anything in /usr/lib/python3.9 was safe to delete

asottile commented 2 years ago

in general nothing in /usr (outside of /usr/local) is "safe to delete" -- those packages are managed by your system package manager

python3-distutils (provided by ubuntu) ships code for 3.8, and 3.9
