Test failure when building debian package

[anoteng]

Dear developers,

I am currently working on getting STA into Debian as a replacement for Scantailor which was removed when QT4 was removed. We are very near being able to upload, but I have this one issue which I would like to have fixed first. One of the tests fail:

xvfb-run --server-args="-screen 0 640x480x24" dh_auto_test
	cd obj-x86_64-linux-gnu && make -j1 test ARGS\+=-j1

I am guessing this is related to the fact that we are running the tests using xvfb instead of on a real screen. Any advice on this matter? Full build log here: https://salsa.debian.org/debian/scantailor-advanced/-/jobs/773112

The fastest way is just to disable those tests: make -j1 test ARGS+="-j1 --exclude-regex \"imageproc_.*\""

[anoteng]

Yeah, that works, but I'd prefer if we figured out a way to get the tests running properly.

@anoteng, any news on scantailor-advanced on Debian? Can you upload a version, even if it is not Debian-perfect somewhere?

[anoteng]

@rbrito I just uploaded it built for Ubuntu Groovy here: https://launchpad.net/~andreas-noteng/+archive/ubuntu/scantailor-advanced I'll upload for some more ubuntu versions to the Launchpad PPA. My sponsor has agreed to sponsor the upload to Debian. We just have to figure out these failing hardening checks: https://salsa.debian.org/debian/scantailor-advanced/-/jobs/1459193 Hopefully it'll be uploaded to unstable in a few days.
