"python-is-python2-but-deprecated" will provide "python (= 2.7.17-1)" for the 20.04 LTS release. This is done so that upgrades don't get packages removed, which depend on python. > I wonder if this is intended behavior, or an oversight? it's intended.

Help and patches are appreciated. Please subscribe me to such bug reports with patches.
