Q: As I am trying to set up my scanner to work with Sane and PDF Studio under Linux, I see this error message reading “Failed to start saned.service: Unit saned.service is masked”. How can I resolve this issue?
A: This is a known issue when upgrading to Ubuntu 15.10 or Ubuntu 16.04. You can read more info here: https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/1577137
To resolve this problem, open a terminal window and type in:
sudo systemctl start saned.socket
Make it start automatically on startup with the following command:
sudo systemctl enable saned.socket
Check if saned.socket is running with the command below:
sudo systemctl status saned.socket
Restart your computer and try to scan again.
