package nplan 0.36.3 failed to install/upgrade: problemi con le dipendenze - lasciato non configurato

[Danilo Luchini]

trying to install different software system report a Python error.
Also running apt-get autoremove (in superuser mode) reports error "The python3 package is not yet configured."

I did not have any particular problems while running Ubuntu.
Sometimes the system freezes when I analyze 3D maps and I have other applications open. I think it happens when I fill the RAM. (I tried to wait over an hour to verify that it was not just slow swap)
