** Changed in: sane-backends (Ubuntu)
Status: Expired => New
** Description changed:
When running scanimage -L on a remote system no scanner is found.
when running scanimage -L on local system (where saned is run) finds the
scanners.
when running scaned in debug mode I can see the remote system request a
list of scanner but no list is returned to scanimge -L. This tell me the
network setups are working and access control is also working. It just
does not find the scanner under saned but finds it under scanimage -L
I have remove saned stuff from systemd so I can run saned by hand
output from scanimage on local system (where saned is run)

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
