Release version of sane-airscan not working for me on openSUSE Tumbleweed #340

Closed dhwalker closed 3 months ago

dhwalker commented 3 months ago

Sane-airscan stopped working for me recently on recent Tumbleweed snapshots. On Tumbleweed 20240512, aarch64, xsane displays a "No devices available" message and does not start. Airscan-discover does find it however:

    > airscan-discover
     [devices]
       Canon MF650C Series = [http://192.168.1.130:80/eSCL/](http://192.168.1.130/eSCL/), eSCL
       Canon MF650C Series = http://192.168.1.130/active/msu/scan, WSD

After some discussion on https://bugzilla.suse.com/show_bug.cgi?id=1221512 (" Bug 1221512 - scanner MFC-J5620DW not anymore recognized by xsane or YaST2"), I found that the sane-airscan-unstable package in home:pzz works for me. So, I have two requests:

Thanks, and particularly thanks for sane-airscan.

Hi @dhwalker,

May I see the protocol trace? To enable it, please uncomment the following lines in the /etc/sane.d/airscan.conf file:

[debug]
trace = ~/airscan/trace

Directory ~/airscan/trace will be created automatically and trace files will be written there.

For now I only need the *.log files, *.tar files are not needed.

dhwalker commented 3 months ago

Thanks for responding, @alexpevzner.

The ~/airscan/trace directory is not created (and no .log or .tar files are created) when using sane-airscan. I am attaching the *.log files for sane-airscan-unstable.

Also, I just noticed that the zypper package list I provided above was from my aarch64 system. Both of these tests just now (with and without -unstable) were done on my x86_64 laptop.

Looks that sane-airscan doesn't load at all. Could you please run ldd /usr/lib64/sane/libsane-airscan.so.1 and show me output?

Probably some libraries that sane-airscan depends on is missed. I bet it is libtiff, I've recently added dependency on it.

If installing libtiff RPM helps, please let me know and report it to SUSE too, they should update their RPM .spec file.

Interesting. The sane-airscan package doesn't even have /usr/lib64/sane/libsane-airscan.so.1. Here's some information:

However... As I was poking around, I found there's a libsane-airscan1 package that contains (only) /usr/lib64/sane/libsane-airscan.so.1. I installed it with sane-airscan, and now xsane starts and finds my scanner. I'm not sure why libsane-airscan1 is a separate package, but it at least it should be required by sane-airscan. If that sounds right to you, I'll send that fix to the Tumbleweed maintainers.

Hi @dhwalker,

yes, you are absolutely correct, the problem is in the missed dependency. Please, report it to the Tumbleweed maintainers.

My own packages brings everything (airscan-discover + sane-airscan) in one single RPM. For some strange reason, Fedora comes with two packages, like SUSE, but with correct dependency between them. SUSE seems have repeated it after Fedora, but missed dependency.

So I close the issue, as resolved and hope SUSE will eventually fix their side too.

Thanks for you help!
