8.10. Removing the live patching package

Procedure

1. Select the live patching package:

   # dnf list installed | grep kpatch-patch
   kpatch-patch-6.12.0-0.el10_0.x86_64        0-0.el10        @@commandline
   …​

   The example output lists live patching packages that you installed.

2. Remove the live patching package:

   # dnf remove kpatch-patch-6.12.0-0.el10_0.x86_64

   When a live patching package is removed, the kernel remains patched until the next reboot, but the kernel patch module is removed from disk. On future reboot, the corresponding kernel will no longer be patched.

3. Reboot your system.

4. Verify the live patching package is removed:

   # dnf list installed | grep kpatch-patch

   The command displays no output if the package has been successfully removed.

Verification

1. Verify the kernel live patching solution is disabled:

   # kpatch list
   Loaded patch modules:

   The example output shows that the kernel is not patched and the live patching solution is not active because there are no patch modules that are currently loaded.
