HP-Plugin fail , HPLIP

I use Ubuntu 16.04 LTS . HPLIP 3.16.3 comes with this . I have bought a new printer LaserJet Pro MFP M130nw which requires a minimum of HPLIP 3.16.11.

I downloaded from the HP Developer website the Automatic Installer (.run file ) Download HPLIP 3.20.5 . and then ran the Automatic Installer .

The process went well until the HP-PLUGIN failed -see log below

Done.

A newbie question - how do I install “Python gobject/dbus “ ?

This worked for me . Now Plug-in installation successful .

Install apparmor utils

sudo apt-get install apparmor-utils

Run

sudo aa-disable /usr/share/hplip/plugin.py

Run as normal user, not as root:
