HPLIP

hp-plugin terminates successfully but hp-setup doesn't recognize

Asked by Richard

Hi,

I'm trying to install HPLIP 3.18.12 on Ubuntu 18.04. So I dowloaded the installer and started it. I use all the defaults, everything seems to work fine. The plug-in installation starts, works fine also. It finishes successfully but the I get the following message:

error: The device you are trying to setup requires a binary plug-in. Some functionalities may not work as expected without plug-ins. Please run 'hp-plugin' as normal user to install plug-ins. Visit http://hplipopensource.com for more infomation.

I confirm this message a return to the point where I can start the installation of the plug-in, which again completes successfully. But guess what - I get the error message again.

I also tried to run hp-plugin and hp-setup seperately with the same result. hp-plugin alone works fine. When I call hp-setup it calls hp-plugin again, which again completes successfully but obviously hp-setup doesn't recognize the plugin and I am in the loop again.

Is someone here who might have an idea where I can start looking for a solution to the problem? Googleing it isn't very helpful.

Thanks a lot

Rich

I just installed hplip 3.19.5 on my SUSE LEAP 15.0 box, and encountered the same problem. But it appears to be a mere annoyance. I just killed the Konsole window (I'm using the KDE Plasma desktop) the installation was running in, and invoked "hp-toolbox" via the command line interface, and everything seems to be working fine. I can use my printer, and my scanner works -- I'm a happy camper.

Incidentally, I had previously installed hplip on several different SUSE distros, and I have never run into this problem before. The previous version I had installed from SourceForge was 3.18.10 ... don't remember the previous version numbers, but I've been through a bunch of them. One other difference I noticed on 3.19.5 is that I couldn't ignore the plugin installation. If I said "skip", the setup program threw me right back into the plugin dialogue. Very frustrating, but ultimately meaningless.

same problem here, installed hplip on Debian 10. hp-plugin says "Done. Plug-in installation successful", but toolbox still asks to install plugin when a printer is connected. doctor complains (or crashed on) missing header, not sure if it's relevant.

aha, so the trick was to run hp-setup in terminal, give it a -i flag if needed.
even after successfully setting up the printer, the GUI setup *still* asked to install the plugin, so it's probably a bug

Can you help with this problem?
