Here is a script that will update your kernel to version 3.2 release candidate 2. Use on your own risk it might break your system. I tested it on a 32 bit system and my system runs without any problems.
Download the script for your system and extract the contents into your downloads folder. Open a terminal window (press Ctrl+Alt+T) and to make the script executable copy+paste the following line in the terminal window:
For 32 bit systems:
chmod +x Downloads/upgrade-kernel-to-3.2-rc2-32bit
For 64 bit systems:
chmod +x Downloads/upgrade-kernel-to-3.2-rc2-64bit
To run the script copy+paste the following line in your terminal window:
For 32 Bit Systems:
sudo ./Downloads/upgrade-kernel-to-3.2-rc2-32bit
For 64 Bit Systems:
sudo ./Downloads/upgrade-kernel-to-3.2-rc2-64bit
Download the script for 32 bit systems
Download the script for 64 bit systems
If you want to do the upgrade yourself open a terminal window and copy+paste the following lines:
