1. Update Package Metadata
Always refresh the repository cache first:
2. Update All Packages (Including Kernel)
The simplest way is:
This pulls in the latest kernel available in the AlmaLinux repositories, along with other packages.
3. (Optional) Install the Latest Kernel Explicitly
If you only want to update the kernel:
4. Verify Installed Kernels
List all installed kernels:
5. Reboot Into the New Kernel
After the update, reboot:
6. Confirm the Running Kernel
After reboot, check your active kernel version:
???? Pro Tip:
-
AlmaLinux normally installs new kernels side-by-side (doesn’t overwrite the old one).
-
The GRUB bootloader lets you choose between them if something breaks.
-
If you want the absolutely latest mainline kernels (not just the stable AlmaLinux ones), you’d enable the ELRepo repository and install from there.
