I checked the whole procedure on a fresh 16.04 install. To start saned.socket first I needed to run
`sudo systemctl start saned.socket` However, in /usr/share/doc/sane-utils/README.Debian I found the solution: To use socket.saned from startup, you have to run `sudo systemctl enable saned.socket` once. The terminal tells me: `Created symlink from /etc/systemd/system/sockets.target.wants/saned.socket to /lib/systemd/system/saned.socket.` On the next reboot saned.socket starts right away. This explains why it was started on my working machine; I definitely tried that command in my attempts to start saned... If you don't want that automatic start anymore, it has do be disabled again: `sudo systemctl disable saned.socket` So I would conclude: This is not a bug, but a feature ;-) -- 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: saned.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
