Xiaobian to share with you how to upgrade the Linux system kernel, I believe most people still do not know how, so share this article for everyone's reference, I hope you have a lot of harvest after reading this article, let's go to understand it together!

View current kernel Open Terminal Execution:

vincent@dell-Inspiron-7559 Dir:~ ····$uname -r 4.15.0-32-generic123 The current computer kernel is version 4.15. Generally, we upgrade the kernel to a higher version.

There are a lot of addresses for downloading kernels, but I mainly use the following two:

Download Linux kernel on github

Download Linux kernel from ubuntu repository

What files does the kernel need to download?

Ubuntu 18.04 uses kernel version 4.15, and Linux mint 19 uses kernel version 4.15.

There are installation differences between versions 4.16 and 4.17:

Here are the file selections for version 4.16:

Here are the file selections for version 4.17:

The installation sequence is sudo dpkg -i ***.deb.

First install linux-headers-4.17.0-041700_4.17.0-041700.201806041953_all.deb

Install linux-headers-4.17.0-041700-generic_4.17.0-041700.201806041953_amd64.deb

Install linux-modules-4.17.0-041700-generic_4.17.0-041700.201806041953_amd64.deb

install linux-image-unsigned-4.17.0-041700-generic_4.17.0-041700.201806041953_amd64.deb

For kernel versions 4.16 and earlier, this file is not available and does not need to be installed.

Restart after installation is complete.

Unloading the kernel

You can see that the system has multiple kernel versions installed, including headers and images, which can be removed to uninstall older kernels.

For example, delete the 4.4.0-22 kernel, we see that there are only headers above, so we can do this:

sudo apt-get remove --purge linux-headers-4.4.0-22 sudo apt-get remove --purge linux-image-4.2.0-22-generic123 and so on.

Then the terminal executes:

sudo apt-get autoclean sudo apt-get autoremove12 Then restart your computer.
