fedora updates so fast that we have to remove some old kernels.
The kernels are in the /boot directory.
fllow the commands:
Command:$rpm -qa | grep kernel look at the kernels on fedora
Command:$uname -r look at the kernel we currently use
If there are two or more kernels on fedora, we should remove the others except the currently one.
Command:$sudo yum remove kernle-3.9……….. remove the other kernels.
I do not recommend you use the Command:$sudo rpm -e …….. , for the rpm -e just remove the old kernels, however the yum remove will not only remove the old kernels but also modifed the start-up action.
