Description Martin Minar 2011-03-18 10:44:48 UTC

Description of problem:
yum fails when /var/cache/yum/rhnplugin.repos contain name of channel that is not present in cache structure (eg. there is no repo.xml) in /var/cache/yum/<channel_name>

Version-Release number of selected component (if applicable):
yum-rhn-plugin-1.4.4-1.el5 (on machine with Spacewalk)

How reproducible:
Alway

Steps to Reproduce:
1. Register into Satellite and channel
2. Manually remove SystemID and repository data
3. Try yum repolist
  
Actual results:
]# yum repolist
Loaded plugins: rhnplugin
This system is not registered with RHN.
RHN Satellite or RHN Classic support will be disabled.
file://var/cache/yum/test-i386-0/repodata/repomd.xml: [Errno 5] OSError: [Errno 2] No such file or directory: '/cache/yum/test-i386-0/repodata/repomd.xml'
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: test-i386-0. Please verify its path and try again

Expected results:
Cache problems should not stop yum operation from finishing.

Additional info:
It is general problem - yum install will return same error.

Workaround is deleting of /var/cache/yum/rhnplugin.repos file.

Fixed in spacewalk nightly
commit 44955186189e3a60afa07e6e4d1b5c9710b2e61c
    688870 - also check whether cached repo is valid

Comment 5 Miroslav Suchý 2011-04-01 20:23:20 UTC

I think that https://bugzilla.redhat.com/show_bug.cgi?id=690234#c5 can solve #4 as side effect. Have to test it...
