For old Linux users, if a new version of the Linux kernel is released, how can you delete the old Ubuntu Linux kernel? I hope this article will help you learn about the Linux kernel. First, use the following command to list all installed kernels. In the following table, the kernel files with images are used. Select the package to be uninstalled and use apt-get to uninstall the package.

The specific uninstall method is

Sudo apt-get remove Linux-image-2.6.24-16-generic
Sudo apt-get remove Linux-headers-2.6.24-16-generic

In this way, the kernel files can be automatically deleted and the disk space can be released.

In addition, you need to record a command.

Uname-

Use this command to view the Kernel used by the current system.

After uninstallation, there are other options in the Start menu, so we need to modify the Start menu,

Run the following command to open menu. lst:

Sudo gedit/boot/grub/menu. lst

Find the unnecessary menu and delete it. Remember to modify the default value and the default startup Item! In this way, the old Linux kernel is successfully deleted.
