Description Karel Srot 2013-05-24 19:34:29 UTC

encountered on RHEL-6.4 with yum-3.2.29-40.el6

+++ This bug was initially created as a clone of Bug #842031 +++

yum install xxx with one bad repository  with skip_if_unavailable=1 aborts entirely instead of just skipping that bad repository.

Note in my case there is no 404, but:


[paul@bofh vala]$ sudo yum install vala

http://download.lab.bos.redhat.com/devel/dmach/repos/XXXXXXX/fedora/17/x86_64/repodata/repomd.xml: [Errno 14] curl#6 - "Couldn't resolve host"
Trying other mirror.
Error: failure: repodata/repomd.xml from XXXXXXX-fedora: [Errno 256] No more mirrors to try.

because my VPN is down, it is not be able to resolve the internal only dns entry, so it should ignore this repository.

Comment 1 Zdeněk Pavlas 2013-05-28 06:38:54 UTC

I thought this was fixed already.. Does it fail with --noplugins, too?  The skip_if_unavailable is in effect when requesting "primary" or "all" metadata only.

It might be the langpack plugin, asking for "comps"..

Comment 2 Jim 2013-07-25 19:15:16 UTC

I can confirm that this bug is still in effect with the "--noplugins" flag.

Comment 3 Jim 2013-07-25 19:16:18 UTC

But only for certain yum commands. "yum install" works, but "yum remove" does not.

Comment 4 Zdeněk Pavlas 2013-07-29 08:24:34 UTC

That's possible, "yum remove" does not set up repos unless dependencies need to be resolved.. but most "simple" package removals work, I assume?  Seems to be fixed upstream already (complex removals work, skipping unreachable repositories).  Do you have a "yum remove" reproducer?

Comment 5 Jim 2013-11-25 17:31:52 UTC

This is still an issue in the newest version of rhel (6.4), with trivial removals:

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodiges


All of my repos have "skip_if_unavailable=1"

I can't reproduce it on 6.5, could you please provide a reproducer?
