How To Install microcode_ctl on Rocky Linux 8
In this tutorial we learn how to install microcode_ctl on Rocky Linux 8. microcode_ctl is CPU microcode updates for Intel x86 processors
Introduction
In this tutorial we learn how to install microcode_ctl on Rocky Linux 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 Rocky Linux 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 Rocky Linux 8 Using dnf
Update yum database with dnf using the following command.
sudo dnf makecache --refresh
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 Rocky Linux 8 Using yum
Update yum database with yum using the following command.
sudo yum makecache --refresh
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 Rocky Linux 8
To uninstall only the microcode_ctl package we can use the following command:
sudo dnf remove microcode_ctl
