units: cannot open file '/root/.units': Permission denied

I'm trying to get scanbd to call sane-scan-pdf when pressing the scan button on my Fujitsu S1300i.

When I run scanbd with sudo SANE_CONFIG_DIR=/etc/scanbd scanbd -d7 -f and press the scan button, I get the following debug output. Note the two lines units: cannot open file '/root/.units': Permission denied.

I don't know how to fix this...

Well, after posting this I found #16, which eventually solved it - I had to update the script that calls scan,

from

#!/bin/sh
now=`date +"%Y-%m-%d-%H%M"`
/home/username/sane-scan-pdf/scan -d -r 300 -v -m Lineart --skip-empty-pages -o /home/username/scans/scan-$now.pdf

to

#!/bin/sh
now=`date +"%Y-%m-%d-%H%M"`
/home/username/sane-scan-pdf/scan --device "" --no-default-size -d -r 300 -v -m Lineart --skip-empty-pages -o /home/username/scans/scan-$now.pdf

--device "" fixed the scanadf: open of device fujitsu failed: Invalid argument error,
--no-default-size fixed the units: cannot open file '/root/.units': Permission denied error.

And then it scanned, albeit 15 seconds or so after pressing the button.

/edit: Your comment in #39 (comment) about calling scanadf without the -d parameter fixed it for me too, I changed the --device "" parameter to --device "epjitsu" which also fixed the delay.

Anyway, I'll close this.
