Package: ipp-usb Version: 0.9.10-2 Severity: normal An installation of ipp-usb is crippled when the device is not discoverable on the the loopback interface. avahi-daemon is needed to expose it on any interface. I also wonder whether ipp-usb.service should have Wants=avahi-daemon.service replaced by Requires=avahi-daemon.service There is a precedent in #82745. Regards, Brian.
