The report is now 2 years old, so I'm not sore if anyone will still read or follow this, but I don't think it's related to policykit, not even related to simple-scan.
I got the same message recently, and it's probably related to the hpaio backend of sane (included in hplib). There's a bugreport on this here: https://bugs.launchpad.net/hplip/+bug/1996438 As a workaround, when no HP scanner is used, you can disable this e.g. by editing `/etc/sane.d/dll.d/hplib` and commenting out the only included library there: ==== # dll.conf snippet for hplip # #hpaio ==== -- 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: New 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.
