I am using Ubuntu on my server, and I want to update it to the latest version of the Linux kernel. I am using aapanel. In the security section, I can see a warning that my current kernel has a security flaw and I need to install the latest version. I am not sure how to do it. Can someone explain the steps to upgrade the kernel?
Is it safe to update the kernel directly, or do I need to do something else before updating? I also want to know how to check my current kernel version.
You can follow the steps below to update Ubuntu latest kernel version is easy:
You can check the kernel version you are currently using by running this command in the terminal:
uname -r
Run this command to update the local package list. This command gets the latest information about available packages from the sources set up on your system.
sudo apt update
To update the installed packages, including the kernel, to the latest versions available, run this command:
sudo apt upgrade
After the installation is complete, reboot your system to start using the new kernel:
reboot
After rebooting, you can check the new kernel version by using the uname -r command again. It should show the updated version.
