Setup cannot continue. Exiting. Never seen this before.

The Debian and Ubuntu packages are (given an inconsequential Ubuntu tweak or two) identical. See the changelogs. I do not know where that leaves us. Upstream is at https://bugs.launchpad.net/hplip/ Please inform us of the URL of your post if you contact them. I'd purge and delete everything hplip related and try again from a terminal. Not having the printer makes testing impossible for us. Regards, Brian.
