Periodically new devices and technology coming out and it\u2019s important to keep our Linux system kernel up-to-date if we want to get the most of out it.<\/p>\n

Moreover, updating system kernel will ease us to take advantage of new kernel functions and also it helps us to protect ourselves from vulnerabilities that have been found in earlier versions.<\/p>\n

Ready to update your kernel on Ubuntu and Debian or one of their derivatives such as Linux Mint? If so, keep reading!<\/p>\n

Check Installed Kernel Version<\/h3>\n

To find the current version of installed kernel on our system we can do:<\/p>\n

$ uname -sr<\/pre>\n
The following shows the output of the above command in a\u00a0Ubuntu 18.04<\/strong>\u00a0server:<\/p>\n
Linux 4.15.0-42-generic\r\n<\/pre>\n
Upgrading Kernel in Ubuntu Server<\/h3>\n
To upgrade the kernel in\u00a0Ubuntu<\/strong>, go to\u00a0http:\/\/kernel.ubuntu.com\/~kernel-ppa\/mainline\/<\/a>\u00a0and choose the desired version (Kernel 5.0<\/strong>\u00a0is the latest at the time of writing) from the list by clicking on it.<\/p>\n
Next, download the\u00a0.deb<\/code>\u00a0files for your system architecture using\u00a0wget command<\/a>.<\/p>\n
Download Linux Kernel for 32-Bit System<\/h4>\n

Once you\u2019ve downloaded all the above kernel files, now install them as follows:<\/p>\n
$ sudo dpkg -i *.deb\r\n<\/pre>\n

Verify Kernel Version in Ubuntu<\/p>\n<\/div>\n
And that\u2019s it. You are now using a much more recent kernel version than the one installed by default with\u00a0Ubuntu<\/strong>.<\/p>\n
Summary<\/h5>\n
In this article we\u2019ve shown how to easily upgrade the Linux kernel on Ubuntu system. There is yet another procedure which we haven\u2019t showed here as it requires compiling the kernel from source, which is not recommended on production Linux systems.<\/p>\n
If you\u2019re still interested in compiling the kernel as a learning experience, you will get the instructions on how to do it at the\u00a0Kernel Newbies<\/a>\u00a0page.<\/p>\n
