remove the old kernel Ubuntu

Ubuntu always keeps the old kernel when it install a new one, just in case this new one doesn't work well for you.


You can uninstall the old one if you don't use it anymore :

Code:

sudo apt-get remove --purge 2.6.15-23-386*

Doing this will uninstall the packages related to the 2.6.15-23 kernel, like "linux-image-2.6.15-23-386", "linux-restricted-modules-2.6.15-23-386", etc.
