when I tried to update with yum , it says the following error messages.
what could be the issus?
# yum list updates
Loaded plugins: fastestmirror
Determining fastest mirrors
YumRepo Error: All mirror URLs are not using ftp, http[s] or file.
Eg. $releasever is not a valid release or hasnt been released yet/
removing mirrorlist with no valid mirrors: //var/cache/yum/updates/mirrorlist.txt
Error: Cannot find a valid baseurl for repo: updates
Can anyone pls suggest me?
