Announced by Linus Torvalds on July 21st, Linux kernel 3.0 brings nice features, such as Btrfs data scrubbing and automatic defragmentation, Berkeley Packet Filter JIT filtering, unprivileged ICMP_ECHO, XEN Dom0 support, wake on WLAN, lots of new drivers and support for many hardware components, support for Microsoft Kinect, support for Apple iSight webcam, support for AMD Llano Fusion APUs, and much more.
Today’s tutorial is for those of you who want to install Linux kernel 3.0 on their Ubuntu 11.04 (Natty Narwhal) systems. In other words, with this guide, we will teach you, step by step, how to install Linux kernel 3.0 on your existing Ubuntu 11.04 (Natty Narwhal) installation, replacing the old 2.6 kernel.
Step 1 – Downloading Linux kernel 3.0 for Ubuntu 11.04
Download the following files for your architecture, one by one, and place them on your home folder (click on the links below to download them):
For Ubuntu 11.04 32-bit
linux-headers-3.0.0-0300_3.0.0-0300.201107220917_all.deb
linux-headers-3.0.0-0300-generic_3.0.0-0300.201107220917_i386.deb
linux-image-3.0.0-0300-generic_3.0.0-0300.201107220917_i386.deb
For Ubuntu 11.04 64-bit
linux-headers-3.0.0-0300_3.0.0-0300.201107220917_all.deb
linux-headers-3.0.0-0300-generic_3.0.0-0300.201107220917_amd64.deb
linux-image-3.0.0-0300-generic_3.0.0-0300.201107220917_amd64.deb
Step 2 – Install Linux kernel 3.0 on Ubuntu 11.04
Hit the CTRL+ALT+T key combination on your keyboard and paste the following command in the terminal window:
sudo dpkg -i linux-headers-3.0.0-0300_3.0.0-0300.201107220917_all.deb linux-headers-3.0.0-0300-generic_3.0.0-0300.201107220917_i386.deb linux-image-3.0.0-0300-generic_3.0.0-0300.201107220917_i386.deb
Wait for the installation to finish. It should not output any errors. If so, reboot your computer and select the Linux kernel 3.0 entry on your GRUB boot loader.
That’s it! You are now running Linux kernel 3.0 on your Ubuntu 11.04 (Natty Narwhal) operating system. If you encounter any hardware issues with this kernel, you can always reboot your machine and select the old kernel from the GRUB boot loader.
WARNING: Do NOT remove the old Linux kernel packages from your Ubuntu machine!
