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 Desktop Packages, which is subscribed to sane-backends in Ubuntu. https://bugs.launchpad.net/bugs/1577137 Title: saned.service masked and cannot be unmasked Status in sane-backends package in Ubuntu: Confirmed Bug description: After upgrading to 16.04 (from 14.04) I noticed the sane daemon (sane- utils 1.0.25+git20150528-1ubuntu2) was no longer running.
