How to upgrade from CentOS 8.1 to CentOS 8.2

One of the best things about Linux is that we can upgrade between versions with almost no problems. Of course, on CentOS it is also possible to do this. And it’s worth doing because CentOS 8.2 is available and loaded with new features from Red Hat Enterprise Linux. In this post, we will explain how to upgrade from CentOS 8.1 to CentOS 8.2

Why upgrade?

Constantly updating a Linux distribution is a guarantee that you will always be safe. This security is provided by the various patches and updates of critical packages that are released from time to time.

In this sense, CentOS is mostly used as the operating system for many servers. These servers are in charge of being the center of many networks where a lot of information circulates. It is therefore important that security policies are up to date.

So let’s do it.

Upgrade from CentOS 8.1 to CentOS 8.2

To update a Linux operating system, you need to be a root user. So, open a terminal and become a root user.

:~$ su

Next, check out the version of CentOS 8 you’re running.

:~# cat /etc/centos-release

And you’ll have a screen output like the one below:

CentOS Linux release 8.1.1911 (Core)
1.- Check the centos version
1.- Check the centos version

And it’s also a good idea to check the Kernel version. To do this, execute this other command:

:~# uname -r

In my case, this is the screen output I got:

4.18.0-147.8.1.el8_1.x86_64

Now all you have to do is make a general system update using dnf.

:~# dnf update
2.- Upgrade from CentOS 8.1 to CentOS 8.2
2.- Upgrade from CentOS 8.1 to CentOS 8.2

Once the whole process is over, reboot the system.

:~# reboot

When the system boots, become root again and check the system version:

:~# cat /etc/centos-release

This is the screen output:

CentOS Linux release 8.2.2004 (Core)

And also check the kernel:

:~# uname -r

And you will get a screen output similar to this:

4.18.0-193.6.3.el8_2.x86_64
3.- CentOS 8.2 installed
3.- CentOS 8.2 installed

So, this is it. You now have CentOS 8.2 in your system perfectly working and ready.

Enjoy it.
