Ubuntu Kernel Update

This morning a kernel update was downloaded by the software updater. However, menu.lst wasn’t updated. I did this by hand. Now that I’m running 2.6.27-11, I don’t need 2.6.27-7. Here’s how to uninstall it:
On the menu, select System/Administration/Synaptic Package Manager
Click Search and enter linux-image-2. Installed kernels will have a green box to their left. Keep at least the two most recent. For each older one, click its green box and select “mark for removal”, then click the Apply button.
