Updating the kernel by terminal

To update the kernel before others applications, do the right thing:
Open terminal  just clicking alt+ctrl+t and type the following commands:
$ sudo apt-get update

Now search kernel version:

$ apt-cache search kernel-image

Now install kernel by explicitly specifying version number:
$ sudo apt-get install linux-image-x.x.xx-yy-generic

Replace xx.yy with kernel version number. Reboot the system.

Instead of the apt-get is to use aptitude command. First of all you have to install aptitude by terminal:

sudo apt-get aptitude

(see more about aptitude on https://help.ubuntu.com/8.04/serverguide/C/aptitude.html )

after that type the followings commands:

sudo aptitude update
sudo aptitude safe-upgrade
sudo aptitude full-upgrade

Important: this commands update and upgrade all of old fashion applications.
