How To Install microcode_ctl on CentOS 8
microcode_ctl is CPU microcode updates for Intel x86 processors
Introduction
In this tutorial we learn how to install microcode_ctl on CentOS 8.
What is microcode_ctl
This package provides microcode update files for Intel x86 and x86_64 CPUs. The microcode update is volatile and needs to be uploaded on each system boot i.e. it isn’t stored on a CPU permanently; reboot and it reverts back to the old microcode. Package name “microcode_ctl” is historical, as the binary with the same name is no longer used for microcode upload and, as a result, no longer provided.
We can use yum or dnf to install microcode_ctl on CentOS 8. In this tutorial we discuss both methods but you only need to choose one of method to install microcode_ctl.
Install microcode_ctl on CentOS 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
The output should look something like this:
CentOS Linux 8 - AppStream 43 kB/s | 4.3 kB 00:00
CentOS Linux 8 - BaseOS 65 kB/s | 3.9 kB 00:00
CentOS Linux 8 - ContinuousRelease 43 kB/s | 3.0 kB 00:00
CentOS Linux 8 - Extras 23 kB/s | 1.5 kB 00:00
CentOS Linux 8 - FastTrack 40 kB/s | 3.0 kB 00:00
CentOS Linux 8 - HighAvailability 36 kB/s | 3.9 kB 00:00
CentOS Linux 8 - Plus 24 kB/s | 1.5 kB 00:00
CentOS Linux 8 - PowerTools 50 kB/s | 4.3 kB 00:00
Extra Packages for Enterprise Linux Modular 8 - x86_64 13 kB/s | 9.2 kB 00:00
Extra Packages for Enterprise Linux 8 - x86_64 24 kB/s | 8.5 kB 00:00
Metadata cache created.
After updating yum database, We can install microcode_ctl using dnf by running the following command:
sudo dnf -y install microcode_ctl
Install microcode_ctl on CentOS 8 Using yum
Update yum database with yum using the following command.
sudo yum makecache --refresh
The output should look something like this:

Extra Packages for Enterprise Linux 8 - x86_64 24 kB/s | 8.5 kB 00:00
Metadata cache created.
After updating yum database, We can install microcode_ctl using yum by running the following command:
sudo yum -y install microcode_ctl
How To Uninstall microcode_ctl on CentOS 8
To uninstall only the microcode_ctl package we can use the following command:
sudo dnf remove microcode_ctl
