[Aurora-sparc-user] yum assistance, please

[Jay Clukey - Systems Admin.]

Some time ago I upgraded my Ultra5 to v1.92 but now it would appear that 
yum no longer works.

One of the commands I have tried is as follows:

yum check-update

and I get the following error message(s):

Setting up Repo:  base
http://aurora.fedoramirror.net/pub/aurora/build-1.92/sparc/os/Fedora/RPMS/repodata/repomd.xml: 
[Errno 4] IOError: HTTP Error 404: Not Found
Trying other mirror.
Cannot open/read repomd.xml file for repository: base
failure: repodata/repomd.xml from base: [Errno 256] No more mirrors to try.

I am assuming that I need to change the baseurl statement in the base 
section as the URL 
'http://aurora.fedoramirror.net/pub/aurora/build-$releasever/sparc/os/Fed
ora/RPMS ' no longer exists due the the env. variable '$releasever' now 
is set to 1.92 and this directory does not seem to exist; nor on any of 
the mirrors that I have checked.

Any ideas? Do I just set it to the same as the baseurl variable under 
the 'updates-released' section?
