Comment 11 for bug 1818629

I try to change the line 45 on /usr/share/hplip/base/validation.py from "pgp.mit.edu" to "keyserver.ubuntu.com". This modification solve the keyserver issue, but continues with problem on plugin installation:

>HP Linux Imaging and Printing System (ver. 3.19.1)
>Plugin Installer ver. 3.0
>

>Plug-in version: 3.19.1
>Installed HPLIP version: 3.19.1
>Number of files to install: 64

>Plugin installation failed
>error: Python gobject/dbus may be not installed
>error: Plug-in install failed.

So, I temporary download the hplip 3.18.6 version, I change the line 45 like explained before (to solve the keyserver issue) and so, it works.
