After installing clean Centos 5.3 and updating with "yum update" yum starts to fail. I get the following error message YumRepo Error: All mirror URLs are not using ftp, http[s] or file. Eg. 7 is not a valid release or hasnt been released yet/ removing mirrorlist with no valid mirrors: //var/cache/yum/base/mirrorlist.txt It looks like the $releasever variable has value 7. Why does this happen and how do I fix this? Thanks, Sami -------------- next part -------------- An HTML attachment was scrubbed...
