FC 6 yum update Error: Cannot find a valid baseurl for repo: core
 

Are the FC6 repositories shutdown?
I tried to do a yum update and cannot get passed this message:
Error: Cannot find a valid baseurl for repo: core

I upgraded one of my FC6 systems to FC7, hoping I could use yum to do updates, but when I run yum update I get this message:
Loading "installonlyn" plugin

http://download.fedora.redhat.com/pu...ta/repomd.xml: [Errno 14] HTTP Error 404: Date: Wed, 08 Apr 2009 16:02:35 GMT

Trying other mirror.
Error: Cannot open/read repomd.xml file for repository: extras

Update:
It looks like the K12LTSP-extra repository was the problem. I removed that repository and now yum works on the FC7 box.

well it is right, that is a 404, there is no fc7 support (or later) from there. have you installed the correct fc7 repo files? the ones you have are presumably still the originals from fc6.

support for fedora 6 ended 2 years ago .
Please install fedora 10

there is no support for fedora 7 or fedora 8
fedora 8 hit End Of Life this January

True, of course, but don't forget people do still have the right to use it if they want to, and the repo's are still there. It's not always possible to just upgrade on a whim.

When I upgraded to FC6 and then to FC7 I figured the repos were updated as well. When I first did the upgrade to FC6 several weeks ago yum update worked an dI updated FC6 packages.

My problem with upgrading to FC10 is two fold, one don't I need to upgrade to FC8 then FC9 and then FC10? Secondly this system only has a CD drive (no DVD) and all the iso files I can find for FC prior to 10 are DVD only.

If it is safe to go straight from FC6 ro FC10 then I can download the CD iso files. Is it safe to make such a leap?

You can actually download Fedora 10 (FYI...Fedora dropped the "core" when Fedora 7 was released) on a Live CD and do an installation if you'd like...

Note the first option to download a "Live-cd"

Not sure if you can upgrade that way though...
