>From the build logs and history on Salsa, I think this is a regression in https://salsa.debian.org/science-team/v-sim/-/commit/ec9b6f88c88eb2b5e44b13bf0f5bd1355a97f863 "Switch from cdbs to dh" rather than anything to do with the new upstream version specifically. Now that this package is no longer using /usr/share/cdbs/1/class/gnome.mk, there is no longer anything to say that it should use the "gir" debhelper sequence or run dh_girepository, so... it doesn't. As a result, the ${gir:Depends} and ${gir:Provides} are not populated and the dependencies are missing. Please add "Build-Depends: dh-sequence-gir" if you prefer the declarative style (I would personally recommend this), or run dh as "dh $@ --with gir" if you prefer the imperative style. Looking at the build log from Salsa-CI, you probably also want "Build-Depends: dh-sequence-python3", or "dh $@ --with gir,python3". A way to avoid this problem in future would be: when you are doing major build-system surgery, I would suggest doing a build with the old build system first and moving it to a reference directory, then doing a build with the proposed change, running debdiff on the two builds, and repeating until all the differences look intentional or non-problematic. In this case I think you would see that all the Depends for gir1.2-* packages would have disappeared, and that's what is causing the autopkgtest failure. Another way to avoid this problem in future would be to check the build log and see whether the warnings issued by dpkg-gencontrol can be explained away as not being a real problem. In this case, the warnings that tell you you're missing some dh sequences are: dpkg-gencontrol: warning: Depends field of package python3-v-sim: substitution variable ${python3:Depends} used, but is not defined dpkg-gencontrol: warning: Depends field of package gir1.2-v-sim-1.0: substitution variable ${gir:Depends} used, but is not defined I hope this helps, smcv
