The `python-is-python2` package on Ubuntu Focal Fossa
$ sudo apt install python Reading package lists... Done Building dependency tree Reading state information... Done Note, selecting 'python-is-python2' instead of 'python'
It turns out that since the
python package has historically been Python 2, and there’s a separate
python3 package (and the commands match the package names, also
pip3 etc), that default has remained in an attempt to break things for fewer people. Which is nice, but how do I get current, stable python?
sudo apt install python-is-python3
There’s a sister package called
python-is-python3 and installing that makes my
python command use version 3 as I expected! It’s a fairly good solution to the problem but it took me a moment to work out how to install it so I thought I’d write it down for next time! Hope it helps you too :)

Upgrading debian 10 to 11 removed A LOT of things about python, so nagios was not working anymore
Installed python-is-python-3 and all works
