Hello, I got the same Python3 upgrade error. Prior that, I had installed the very latest hplip-3.18.6 from a .run file. I did also install the hplip-3.18.6-plugin.run file.
Reason for this is another bug in the hplip package. Please see: https://bugs.launchpad.net/ubuntu/+source/hplip/+bug/1714659 The default hplip does not work in Ubuntu 18.04 with the GNOME-desktop environment. For example the "simple-scan" application did not start becuse of the systray error in hplip. I tried to alleviate this (systray + app exit) error by installing the hplip from source. It did not help, but I finally managed to disable the hplip`s use of systray.
