I have the same problem, but at least found a workaround. The man-page for saned (http://manpages.ubuntu.com/manpages/xenial/man8/saned.8.html) shows a solution using systemd. Two config-files are needed in /etc/systemd/system, saned.socket and saned@.service.
With those files saned seem to work, even though it is masked. scanimage -L shows the network scanners, and xsane and other programmes can access those scanners without problems. ** Attachment added: "saned@.service" https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1577137/+attachment/4666731/+files/saned%40.service -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1577137 Title: sane service masked and cannot be unmasked To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1577137/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
