- List the installed Linux kernels on your system by the following command:
sudo dpkg --get-selections | grep linux-image
- This would show you all the installed Linux Kernels on your system. Now that you’ll see the latest and older Linux kernels listed. Now let’s say linux-image-3.2.0 is the older Linux kernel installed on your system and linux-image-3.9.4 is the latest Linux kernel. You’ll supposedly remove linux-image-3.2 as it’s the older Linux kernel and you won’t be using it. So basically it’s of no use at all. To remove it execute the following command in Terminal:
sudo apt-get purge linux-image-3.2.0
- Remember! DO NOT remove linux-image-generic. It’s necessary to upgrade Linux kernel for your system.
- Now execute any of the following in Terminal to see whether you’ve successfully removed your older Linux kernel:
dpkg --get-selections | grep linux-im
dpkg --get-selections | grep linux-image
