It does that by connecting to computers on the internet that are repositories for software for your distribution. It caches a copy of each program it downloads and installs, and it keeps a running database of what's installed on your computer, and what's available in the internet repositories. Yum clean all is a command that erases all those programs you already downloaded, and erases the database of programs available in the internet repositories. "yum list kernel" is a command to list both what's installed on your computer, and what's available on the internet - your list command failed because it couldn't perform the second part of the two part command. -- Claude Jones Bluemont, VA, USA
