@Alex Hofmann I was searching the web for my bug, which was exactly the same, and found your comment. I removed hplip + hplip-gui, commented the file `/etc/sane.d/dll.d/hplip` and rebooted. Now I can use simple-scan without being required to enter my password.
My Ubuntu is the vesion 24.10. I just reinstalled both hplip and hplip-gui, and will observe the simple-scan behavior after next time I reboot, just in case editing the `/etc/sane.d/dll.d/hplip` file would not be enough. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to policykit-1 in Ubuntu. https://bugs.launchpad.net/bugs/1926014 Title: simple-scan is trying to start disabled avahi-daemon.service Status in policykit-1 package in Ubuntu: Confirmed Bug description: Hi, I have a fresh installation of Ubuntu desktop 21.04. I stop and disable avahi-daemon.service + avahi-daemon.socket (I don't use these services on my desktop) Then I start "simple-scan" program. After that I see a pop-up window for admin password! It's wrong, no such thing should be there. In previouse release (20.10) it was OK. Thanks.
