Hi,

first: I did several yum clean all's :-)

Thunderbird 38.4.0 is not offered.

I see:
http://mirror.centos.org/centos/6/updates/x86_64/Packages/thunderbird-38.4.0-1.el6.centos.x86_64.rpm - 27-Nov-2015 06:58 - 56M

But:
http://mirror.centos.org/centos/6/updates/x86_64/repodata/repomd.xml - 18-Nov-2015 20:00 - 3.4K

Shouldn't repomd also be updated or am I mistaken?

Thanks
Patrick
