Public bug reported: The package python-requests doesn't declare multi-arch correctly. According to the spec [1], because it's "Architecture: all", I believe "Multi-Arch: foreign" should be specified so that the native package can be installed.
As an example of where this currently fails: $ sudo apt-get install ceph-common:armhf Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. The following information may help to resolve the situation: The following packages have unmet dependencies: ceph-common:armhf : Depends: librbd1:armhf (= 10.2.9-0ubuntu0.16.04.1) but it is not going to be installed Depends: python-cephfs:armhf (= 10.2.9-0ubuntu0.16.04.1) but it is not going to be installed Depends: python-rados:armhf (= 10.2.9-0ubuntu0.16.04.1) but it is not going to be installed Depends: python-rbd:armhf (= 10.2.9-0ubuntu0.16.04.1) but it is not going to be installed Depends: python-requests:armhf but it is not installable Depends: librados2:armhf (>= 0.87) but it is not going to be installed Depends: libradosstriper1:armhf (>= 0.93) but it is not going to be installed Depends: librgw2:armhf (>= 10.2.9) but it is not going to be installed E: Unable to correct problems, you have held broken packages. $ lsb_release -rd Description: Ubuntu 16.04.3 LTS Release: 16.04 $ apt-cache policy python-requests python-requests: Installed: 2.9.1-3 Candidate: 2.9.1-3 Version table: *** 2.9.1-3 500 500 http://de.archive.ubuntu.com/ubuntu xenial/main i386 Packages 500 http://de.archive.ubuntu.com/ubuntu xenial/main amd64 Packages 500 http://ports.ubuntu.com/ubuntu-ports xenial/main armhf Packages 100 /var/lib/dpkg/status https://wiki.ubuntu.com/MultiarchSpec#Dependencies_involving_Architecture:_all_packages ** Affects: python-requests (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/1737973 Title: python-requests doesn't specify Multi-Arch in debian/control To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python-requests/+bug/1737973/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
