I am trying to update HPLIP 3.14.3 to 3.15 but is not available through the software centre thus I am installing it from here.
However I am having difficulties in the automatic installation due to python. In particular, after selecting ubuntu 14.04, I get the error:
warning: Missing REQUIRED dependency: python3-dbus (Python DBus - Python bindings for DBus) warning: This installer cannot install 'python3-dbus' for your distro/OS and/or version.
But I have installed the following:
python IDLE python 3.4 python 3.4 python3-dbus 1.2.0-2build2 (but not D-bus support & debug)
And when I tried to update these option I got:
Requires installation of untrusted packages
How can I overcome this issue? Thank you
