This was one of the error occoured for me while using fedora 8. once i given yum update command to update the whole system.After that when i try to update any software it shows the error "No package marked for update".After this yum update it stoped showing new update information on the panel. So i done a lot of googling find the solution.It is because the repolist is not enabled.Then let me show how i enabled it.
1. open the terminal and get into super user mode. 2. run the command yum clean all. 3. run the command yum repolist enabled.
I would like to make get comment to better my blog. So please leave a comment
