Source: jpeg-xl Version: 0.9.2-9 https://salsa.debian.org/debian-phototools-team/libjxl/-/commit/1ce1fb3ed87 disabled autopkgtests on s390x and some ports architectures (which I don't think make use of debci or similar currently).
I was able to successfully run the autopkgtest on Ubuntu's s390x: https://autopkgtest.ubuntu.com/results/autopkgtest-noble-jbicha-arch2/noble/s390x/j/jpeg-xl/20240630_115747_81fd4@/log.gz dh_auto_test runs successfully on all release architectures too. Therefore, I suggest removing the Architecture line from debian/tests/control. This should allow jpeg-xl to benefit from the autopkgtest "bounty" and be eligible for migration to Testing in 2 days instead of 5 days. Thank you, Jeremy Bícha
