Public bug reported: Per the spec <https://wiki.ubuntu.com/MultiarchSpec#Dependencies_involving_Architecture:_all_packages>, arch: all packages are treated similarily to arch: anythingelse ones.
This means that for an Architecture: all package to satisfy the dependencies of a foreign-architecture package, it must be marked Multi- Arch: foreign or Multi-Arch: allowed. python3-dbusmock is an arch: all package. It's a dependency of libqtdbusmock1, which is transitively a build-dep of ubuntu-system- settings. Since python3-dbusmock isn't M-A: anything, it can't be installed when installing libqtdbusmock1:armhf on a foreign host. How about marking it (and probably python-dbusmock) as M-A: foreign? To reproduce on a machine with foreign arch armhf enabled $ apt-get -aarmhf build-dep ubuntu-system-settings ** Affects: python-dbusmock (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1357388 Title: Mark Multi-Arch: foreign To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python-dbusmock/+bug/1357388/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
