Server 20.04 - sane is not responding

[David Fletcher]

I just found:-

ls -l /usr/lib/systemd/system/sane*
lrwxrwxrwx 1 root root   9 Feb 24 08:39
/usr/lib/systemd/system/saned.service -> /dev/null
-rw-r--r-- 1 root root 309 Feb 11 11:27
/usr/lib/systemd/system/saned at .service
-rw-r--r-- 1 root root 133 Feb 11 11:27
/usr/lib/systemd/system/saned.socket

Surely cannot be correct? The other .service files here are text config
files. I don't understand them at all but they are text files not links
to /dev/null!
