Most people do not understand the knowledge points of this article "Linux how to uninstall the old kernel", so the editor summarizes the following content, detailed content, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "Linux how to uninstall the old kernel" article.

First of all, you can see which kernel is currently in use, and you can get the information through the command: uname-a. For example, on my desktop, it reads:

Magc@magc-desktop:~$ uname-a

Linux magc-desktop 2.6.24-19-rt # 1 SMP PREEMPT RT Thu Aug 21 02:08:03 UTC 2008 i686 GNU/Linux

Then look at the list of all the kernels on the machine to decide which ones need to be deleted:

Run the command: dpkg-get-selections | grep linux, for example, my local display is as follows:

Magc@magc-desktop:~$ dpkg-get-selections | grep linux

Libselinux1 install

Linux-generic install

Linux-headers-2.6.24-19 install

Linux-headers-2.6.24-19-generic install

Linux-headers-2.6.24-19-rt install

Linux-headers-2.6.24-21 install

Linux-headers-2.6.24-21-generic install

Linux-headers-2.6.24-21-rt install

Linux-headers-generic install

Linux-headers-rt install

Linux-image-2.6.24-19-generic deinstall

Linux-image-2.6.24-19-rt install

Linux-image-2.6.24-21-generic install

Linux-image-generic install

Linux-image-rt install

Linux-restricted-modules-2.6.24-19-generic deinstall

Linux-restricted-modules-2.6.24-19-rt install

Linux-restricted-modules-2.6.24-21-generic install

Linux-restricted-modules-common install

Linux-restricted-modules-generic install

Linux-restricted-modules-rt install

Linux-rt install

Linux-sound-base install

Linux-ubuntu-modules-2.6.24-19-generic deinstall

Linux-ubuntu-modules-2.6.24-19-rt install

Linux-ubuntu-modules-2.6.24-21-generic install

Util-linux install

Util-linux-locales install

The one with image is the kernel file, so you can see that there are five kernel versions on my machine. I am currently using 2.6.24-19-rt, so I decided to delete other useless kernels.

The command to delete is: sudo apt-get remove linux-image-XXXX

For example, the way to delete the linux-image-2.6.24-19-generic kernel is:

Sudo apt-get remove linux-image-2.6.24-19-generic
