Comment 1 for bug 1547879

Starting with hplip version 3.18.12 the situation became even worse. Now there is no workflow where normal users on Debian Live can just start hp-setup and also install the plug-in in the same step. They run into obscure situations and error messages and have to step back and forward to just install an HP printer.

It all seems to be a problem of your custom build password code. Details are on the mailing lists of Debian Live (and Debian Backports), see here:

We maintain an educational distribution that is used by several thousand teachers and students and on behalf of them I thank you very much in advance for fixing this bug.

Best
