FC6: Metadata file does not match checksum

[Michael Schwendt]

Revisiting the annoying "Metadata file does not match checksum" problem,
since it just came back here like this:

$ ll /var/cache/yum/updates-released/
total 488
-rw-r--r-- 1 root root      0 Oct 10 12:28 cachecookie
drwxr-xr-x 2 root root   4096 Oct 10 12:28 headers
drwxr-xr-x 2 root root   4096 Oct 10 12:28 packages
-rw-r--r-- 1 root root 461224 Oct 10 12:33 primary.xml.gz
-rw-r--r-- 1 root root   1197 Sep 19 00:47 repomd.xml

The cached repomd.xml file is out-of-date from September 19th, and all
the mirrors offer much newer repodata from Oct 8th. The mirrors are
not to blame here, since Yum does not consider downloading a fresh copy.
Instead, it seems it tries to fetch metadata files which match the old
repomd index:

Is this observation right?
