[MM3-users] Should I try to install mailman3 on Kubuntu 20.04?

I have been a happy camper running mailman3 on a vps I rent from a vendor, running CentOS 7.  CentOS 7 is past end of life, so I moving over to a new machine running Kubuntu 20.04 LTS.  I have been searching the intertubes and have seen a bunch of people having headaches trying it.  So...

Is Ubuntu 20.04 cool with mailman3?  Should I go ahead and give it a shot or use a different distro?

Should I do the  apt install, the virtualenv install, or try the docker install?

thanks
