I’d like to install the latest kernel from http://download.opensuse.org/repositories/Kernel:/stable/standard/ in order to test some hardware compatibility.
From what I’ve found online the two options are basically just to specify the kernel version during install:
zypper in kernel-default-4.20....
zypper dup --from kernel....
The first option results in a “must first load kernel” error (or something very similar to that) after selecting the kernel from the grub boot menu.
The second option requests that I uninstall the current kernel with the vendor change to the new repository. I’d like to avoid uninstalling the current kernel. I have multiple kernel versions enabled in the zypp.conf file.
So, my question is, how do I install the new kernel alongside the current Leap 15 kernel while also getting it to boot from grub? Do I just need to update grub somehow, and if so, how should I go about it.? I’m using UEFI boot with multiple hard drives, if that makes any difference.
