Hi.. I just upgrade my FC3 kernel to 2.6.12-1.1381_FC3smp but after upgrade, I got the error message when I typed up2date command. May I know what is the problem ? Actually I feel linux is very confusing. There are so many kernel version and Fedora version. How do I know which version of application is suitable for which kernel ? Anyway to check ? [root@w2 ~]# up2date No interactive mode available Please specify either -l, -u, --nox, or package names as command line arguments.
