Followup-For: Bug #1065258 Control: found -1 1.4.3+dfsg-4 I only checked one, but it's probably the same for all of them. The Breaks+Replaces are not correct, they miss the "contrib" part:
Package: libstarpu-contribrm-1.4-1t64 Source: starpu-contrib Version: 1.4.3+dfsg-4 Installed-Size: 92 Maintainer: Samuel Thibault <sthiba...@debian.org> Architecture: amd64 Replaces: libstarpurm-1.4-1 ^^^^^^^^^^^^^^^^^ Provides: libstarpu-anyrm-1.4-1, libstarpu-contribrm-1.4-1 (= 1.4.3+dfsg-4) Depends: libc6 (>= 2.34), libhwloc15 (>= 2.10.0), libstarpu-contrib-1.4-4t64 (>= 1.4.3+dfsg) Conflicts: libstarpurm-1.4-1t64 Breaks: libstarpurm-1.4-1 (<< 1.4.3+dfsg-4) ^^^^^^^^^^^^^^^^^ And probably you should add a Conflicts: libstarpurm-1.4-1, too, otherwise pre-t64 libstarpurm-1.4-1 and post-t64 libstarpu-contribrm-1.4-1t64 will be co-installable, resulting in another potential file conflict.
