I was inspecting why the autopkgtest of deal.ii fails in the boost 1.90 transition, and at the same time the binNMU's of deal.ii are not migrating. The scheduled autopkgtests fail [1, 2] and are hinting at a missing versioned dependency somewhere in the binaries of deal.ii. The error can be found below. It seems to me that the right binary of deal.ii should either: a. drop the check for the boost version and rely on our autopkgtests to catch issues b. encode the dependency during building of deal.ii on the proper boost binary with a version, such that the binaries of boost and deal.ii have to migrate together and the migration software knows things have to be scheduled together. The test passes in unstable (on amd64 and ppc64) where both updates are available at the same time. The test also passes in testing (on amd64 and ppc64) if I allow both boost-defaults and deal.ii from unstable. 135s In file included from /usr/include/deal.II/base/conditional_ostream.h:18, 135s from /tmp/autopkgtest-lxc.szhuzm4m/downtmp/autopkgtest_tmp/examples/step-50/step-50.cc:26: 135s /usr/include/deal.II/base/config.h:695:17: error: static assertion failed: The version number of boost that you are compiling with does not match the version number of boost found during deal.II's configuration step.
