A simple tutorial for installing an older kernel on Ubuntu.
These days I’ve been working on our SDN project. Our project is based on a customed OVS which used an older version of OVS as its fundation. The problem is, this version of OVS cannot be properly built on a machine with Linux kernel version higher than 3.8 or lower than 2.7. At the beginning I downloaded and installed a Ubuntu 12.04.1 with Linux kernel 3.2.0-29-generic as its original kernel. However, Ubuntu 12.04 is relatively old now and some of its apt sources are out-dated. This caused problems when installing prerequisites for my project. Thus, I figured out a way to install and use an older kernel on the latest version of Ubuntu, so that I can get my project properly built while leveraging the best of latest apt sources. Here’s how I installed linux-3.2.0-56-generic on my Ubuntu 16.04 and boot with it. It’s actually quite simple.
Just download the latest LTS version of Ubuntu (for me now it is 16.04) from its official site and install it with your VMware or anything.
Install Older Kernel
In your newly intalled Ubuntu, use browser and navigate here to download the following files (xxxxxx will be replaced with numbers indicating the kernel version. Assuming you have a 64bit OS):
Then there is one more thing you have to get before installing:
$ sudo apt install -y module-init-tools
After this, move all there files you’ve just downloaded to a new folder and
cd to the new folder and run:
$ sudo dpkg -i *.deb
Boot Into the ‘New’ Kernel
Reboot your computer.
Press left (or right, you should try both)
SHIFT key at the booting stage and log into Grub. Choose your newly installed kernel to boot, and you’re ready to go!
