Comment 1 Lukas Pramuk 2012-11-19 15:24:06 UTC
Description of problem:
spacewalk-repo-sync cannot connect over https +IPv6 [BAD], however:
spacewalk-repo-sync over https + IPv4 [OK]
spacewalk-repo-sync over http + IPv6 [OK]
curl over https +IPv6 [OK] 

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

How reproducible:

Steps to Reproduce:
1. prepare ipv6-only kvm guest
2. @guest: create some simple repo, start httpd to publish the repo via http(s)
3. @host: run spacewalk-repo-sync -c myrepo -u https://kvm/myrepo with traceback
Actual results:
traceback, no connection 

Expected results:
successfull connection

Additional info:

Comment 3 Milan Zázrivec 2012-11-22 16:00:32 UTC
What's happening here is that if you're repo-syncing over https (SSL),
pycurl (which is what repo-sync -> yum libs -> urlgrabber use) returns
the following error:

'Peer certificate cannot be authenticated with known CA certificates'

This error is not properly propagated to spacewalk-repo-sync, or -- if you
will -- is being propagated to the user as the traceback shown above.

This problem can be fixed with the fix contained in bug #807000 and you'll be
able to put the following into your /etc/rhn/spacewalk-repo-sync/yum.conf:



I think this still needs to be investigated closer (there's perhaps
a better solution / fix to the problem here).
