Ubuntu 18.04.1
Tried to customise printers to work with local HP network printers (hplip) and failed. Tried to revert back to vanilla set-up and now cupsd will not start.
Where I am at is I have purged hplip and cups, then reinstalled cups (apt-get install cups) systems hangs at "setting up cups-daemon" then times-out. Running systemctl does not reveal much:
$systemctl status cups.service

So I suspect I have done something to my network manager. Is there a simple fix please as I seem to have a rouge widget?
