Description Jiri Stransky 2015-06-08 12:07:48 UTC
Description of problem:

python-cryptography depends on a non-existent package

Error: nothing provides python-ipaddress needed by python-cryptography-0.9-1.fc21.x86_64

Version-Release number of selected component (if applicable):

python-cryptography-0.9-1.fc21.x86_64


How reproducible:
always


Steps to Reproduce:

yum install python-cryptography

or

dnf install python-cryptography


Additional info:

OpenStack deployment CI is broken because of this, it's a high severity issue for us.

The depcheck test in https://admin.fedoraproject.org/updates/FEDORA-2015-8354/python-cryptography-0.9-1.fc21 actually caught this:

    output: |-
      Build python-cryptography-0.9-1.fc21 failed depcheck
      conflicting requests
      nothing provides python-ipaddress needed by python-cryptography-0.9-1.fc21.x86_64
      conflicting requests
      nothing provides python-ipaddress needed by python-cryptography-0.9-1.fc21.x86_64



Does https://admin.fedoraproject.org/updates/FEDORA-2015-9676/python-ipaddress-1.0.7-2.fc21 fix this?

Comment 2 Nathaniel McCallum 2015-06-09 19:39:52 UTC
https://admin.fedoraproject.org/updates/FEDORA-2015-8385/python-ipaddress-1.0.7-1.fc21

It was pushed to stable today and should be there in the next compose.

Comment 3 Dan Prince 2015-06-09 20:31:53 UTC
Things are still very badly broken because we now have packages which require python-ipaddr and python-ipaddress (which conflict with each other).

The only way I could fix upstream TripleO as things stand was to install both python-ipaddr and python-ipaddress with --nodeps:

https://review.openstack.org/#/c/189745/

Until this is fixed Fedora 21 is unusable w/ upstream TripleO packages...

As a work around we've cherry picked the review above into our CI environment to take the pressure off things...

Comment 4 Nathaniel McCallum 2015-06-10 01:18:46 UTC
I'm not sure what to do here.

python-ipaddress is required for python-cryptography. It is a backport of the ipaddress module from Python 3.x.

Unfortunately, python-ipaddr exposes different stuff in the same namespace used by upstream Python 3.x (and implicitly python-ipaddress).

I'm open to proposals.

Comment 5 Dan Prince 2015-06-10 15:50:15 UTC
Would it make sense to use Obsoletes: python-ipaddr in the python-ipaddress package? It seems like that is the desired behavior you are going for here.

As is the use of Conflicts: breaks quite a few things... for packages that may get installed alongside python-cryptography which require the old python-ipaddr dependency.

Comment 6 Nathaniel McCallum 2015-06-10 16:52:30 UTC
No. python-ipaddr provides a *different* API in the same namespace.

Comment 7 Nathaniel McCallum 2015-06-10 17:32:25 UTC
Alright, with some further digging I think we can remove the conflicts.

The main issue is bojan's comment here: https://admin.fedoraproject.org/updates/FEDORA-2015-8290/python-ipaddress-1.0.7-1.fc21

However, this may just be a bug in pypolicyd-spf. I will remove the conflicts and see if we can track down the bug in pypolicyd-spf.
