mirrors errors

Mon Dec 12 09:47:42 UTC 2016

Hi Eyal,

This does not look like a mirror issue but a MetaLink one.
MetaLink is a security plugin for yum [1] and I saw the same
issue last week so MetaLink may have been broken at that time.

Basically what it does is fetches a file like [2] and checks
if the mirrors received from the mirrorlist are present there.
Maybe it does some other checks, but the point of this is
protection against stale/rogue mirrors. 

I think we should just disable MetaLink on our CI slaves as
we don't rely on latest fedora software versions anyway.

Doesn't seem to be we're over the unavailable mirrors issue with the new
repos added to STD CI:

Lets start working on mirroring the relevant repos to mirrors.phx.ovirt.org
and get control over the update process.

DEBUG util.py:421:   One of the configured repositories failed (updates),
DEBUG util.py:421:   and yum doesn't have enough cached data to
continue. At this point the only
DEBUG util.py:421:   safe thing yum can do is fail. There are a few
ways to work "fix" this:
DEBUG util.py:421:       1. Contact the upstream for the repository
and get them to fix the problem.
DEBUG util.py:421:       2. Reconfigure the baseurl/etc. for the
repository, to point to a working
DEBUG util.py:421:          upstream. This is most often useful if you
are using a newer
DEBUG util.py:421:          distribution release than is supported by
the repository (and the
DEBUG util.py:421:          packages for the previous distribution
release still work).
DEBUG util.py:421:       3. Disable the repository, so yum won't use
it by default. Yum will then
DEBUG util.py:421:          just ignore the repository until you
permanently enable it again or use
DEBUG util.py:421:          --enablerepo for temporary usage:
DEBUG util.py:421:              yum-config-manager --disable updates
DEBUG util.py:421:       4. Configure the failing repository to be
skipped, if it is unavailable.
DEBUG util.py:421:          Note that yum will try to contact the
repo. when it runs most commands,
DEBUG util.py:421:          so will have to try and fail each time
(and thus. yum will be be much
DEBUG util.py:421:          slower). If it is a very temporary problem
though, this is often a nice
DEBUG util.py:421:          compromise:
DEBUG util.py:421:              yum-config-manager --save
--setopt=updates.skip_if_unavailable=true
