I don't know what's wrong with my packages or ppas but every time I try to run sudo apt update in my zsh terminal, it logs this error:

I just know it's a python error but I don't know what it means. Os is kubuntu 20.04, and python3 version is 3.9.9
python3 --versionare correct for your unstated release; as python3 errors are commonly the result of incorrect python3 version changes. – guiverc Dec 27 '21 at 08:10python3the machine comes with; so you'll have to leave the default python3 be what the machine comes with (python3defaults to 3.9.9 for my newer release) and use a second/newer python3 for your scripts that rely on it; OR don't use Ubuntu tools that rely on python3 being the default (eg. live withapt& like tools that are designed/tested to work only with the default python3). As I said do it properly (and don't change the default!) Your question/problem here is because you changed the python3 version incorrectly. – guiverc Dec 27 '21 at 08:48
