python3-dbus not installed

Linux distro: Mint 20.3
I have done: sudo apt-get install python3-dbus after first failed installation attempt
it reports latest version installed:
Reading package lists... Done
Building dependency tree
Reading state information... Done
python3-dbus is already the newest version (1.2.16-1build1).

Running sh hplip-3.22.10.run again still results in:
