OK, it seems there are a few broken things here. I think you have a
repo from openSUSE, quite possibly to get an up-to-date
sane-airscan, but it's not all really working very well.<br>
<br>
First off, these command lines are all very well, but I hardly ever
use them unless I have to.<br>
If you are running a Desktop, then I would definitely check out the
"Software Sources" utility that you can find in the Administration
menu.<br>
If you are not running a desktop, let me know then we can pursue the
commands, but I prefer not to go down that road if possible :)<br>
<br>
However, if you are, fire that up:<br>
<br>
1) Remove the key for pzz, the one that you should see as listed as
"invalid key resource" above.<br>
2) Remove the pzz repository<br>
<br>
Also, it looks like you have both sane-release and sane-git
repositories there. They should be able to co-exist, but I would
remove the one that you don't require. It will just complicate
things.<br>
If you want bleeding edge SANE (that might break from time to time),
remove sane-release repository.<br>
If you want the stable most recent release of 1.0.31, then remove
the sane-git repository.<br>
<br>
Then when you finish with that, in a terminal do (more for
paranoia):<br>
<br>
$ sudo apt-get remove libsane1 xsane<br>
$ sudo apt-get update<br>
$ sudo apt-get install xsane libsane1<br>
<br>
And it should install SANE 1.0.31<br>
<br>
And let us know how you got on.<br>
It might take a couple of iterations, but we will definitely get
there.<br>
<br>
Cheers,<br>
Ralph<br>
