Hello,

Looking at
https://mirrorcache.opensuse.org/repositories/home:/vbernat/CentOS_7/repodata/primary.xml.gz.mirrorlist,
it mentions `widehat.opensuse.org` which does not resolve. Some mirrors also
seem late. For example
https://ftp.lysator.liu.se/pub/opensuse/repositories/home:/vbernat/CentOS_7/repodata/primary.xml.gz
has 1.0.11,
https://ftp.gwdg.de/pub/opensuse/repositories/home:/vbernat/CentOS_7/repodata/primary.xml.gz
has 1.0.12 as well as some others.
https://mirror.firstyear.id.au/repositories/home:/vbernat/CentOS_7/repodata/primary.xml.gz
seems up-to-date.

See https://github.com/lldpd/lldpd/issues/495 for the original report. It also
mentions that yum sometimes fail with:

```
https://download.opensuse.org/repositories/home:/vbernat/CentOS_7/repodata/primary.xml.gz:
[Errno -1] Metadata file does not match checksum
```

Dunno if download.opensuse.org relies on the mirrorlist or if it is another
different problem.
