SANE: Error during device I/O (code=9) - solved on openSUSE

[yogi70]

Hi Users,

after updating my system from openSuSE 15.3 => 15.4 i could not use scan-tools like hp-scan any more. I always get the following error:

SANE: Error during device I/O (code=9)

/var/log/messages reports something like:
/hp-scan: common/utils.c 178: validate_plugin_version() Plugin version[3.22.2] mismatch with HPLIP version[3.22.10]

running
> hp-check -t
could not install missing rpms like pyqt, pyqt-notify

After searching serveral days now I found a solution:

In the /var/log/messages I found the information that a Plugin-Version did not match, but running

> hp-plugin -i
did not work. I need to run

> aa-disable /usr/share/hplip/plugin.py

from package apparmor-utils do disable the AppArmor security profile for the hplip/plugin.py before I could sucessfully download the needed plugins.

looks like several users had the same issue before and I hope this would help them.
