I got a weird problem with DNS. Turned out to be a bug in resolvd. I am leaving this here for others. Eventually is also relevant for the developers. This error will appear in the virtualmin check that happens just after the installation. It will say something about a missing 127.0.0.1 in thee DNS servers, instead the address 127.0.0.53 is listed.
Debian 10. Fresh install
sudo rm -f /etc/resolv.conf
sudo ln -s /run/systemd/resolve/resolv.conf /etc/resolv.conf
