I ran into this exact issue last night -
http://www.iotti.biz/?p=433
When a computer is connected via IPv4 but the IPv4 a repo host connects to is not available, yum then tries the IPv6 address and will fail with a confusing message telling you it failed to connect to the IPv6 address.
I don't know if there is a way for yum to figure out whether the current network connection to the Internet is IPv4 or IPv6.
But if there is a way, it might make a usability improvement. A lot of people have no idea what IPv6 is and would be confused.
I was confused myself at first, wondering if DHCP pulled in IPv6 from the router.
If your DNS answers IPv6, it will have prefence over IPv4. You can set
ip_resolve=4 in your yum.conf
The issue is the yum server was down, so IPv4 didn't work.
Once that server was back up (third party repo) it of course worked no
issue.
The issue is the error message, while a technically correct one, is one
that is not very user friendly and can be confusing to people who are
not dual-stack.
It could be improved.
