Since, perhaps, two or three days ago I get this error message when the automatic update runs:

Problem connecting to a software origin
File '/repodata/repomd.xml' not found on medium
'http://download.opensuse.org/repositories/devel:/openQA/openSUSE_12.3/'

When I run apper software update manually, the error message is:

There was a (possibly temporary) problem connecting to a software origins

Details:

File '/repodata/repomd.xml' not found on medium
'http://download.opensuse.org/repositories/devel:/openQA/openSUSE_12.3/'

I haven't a clue where to go from here. Has anyone reported a similar error?
