According to https://bugzilla.redhat.com/show_bug.cgi?id=753149#c5 packages that go from noarch to arch need to have a versioned obsolete to properly upgrade. I'm currently gathering more information to figure out whether we need a guideline and what it should look like if so.
This would affect any package that changes arch, the direction of change doesn't matter, whether it's arch->noarch or noarch->arch
IMO, this is a bug in yum and should be fixed there ASAP.
James, can you shed some light on what we should do here? Maybe we can come up with a draft by next week's meeting?
So, as far as I know it "works" in yum ... we have a bunch of testcases for all the various arch changing upgrades (including multilib), and they always pass. However people tend to hit problems when obsoletes aren't used, and rpm has it's own "quirks" (and they tend to be in the file colouring etc. code paths).
I'm mostly fine with just saying "we'll fix it in yum", but Panu will have to sign off on the same for rpm.
bump.... any update?
There's a current F16 update candidate which appears to have this problem:
https://admin.fedoraproject.org/updates/FEDORA-2012-5087/polkit-0.103-1.fc16
With a clean install of F16 x86_64, with all packages from updates but nothing from updates-testing, if I enable updates-testing and do 'yum update', yum wants to install both the i686 and x86_64 versions of polkit to replace the noarch polkit-desktop-policy. So there definitely is a problem in at least one real-world case here.
The polkit-0.103-1 spec states:
Obsoletes: polkit-desktop-policy < 0.103[[BR]] Provides: polkit-desktop-policy = 0.103
