I'm currently using a kernel from Kernel:/stable:/Backport/standard/ (as explained in bug 1212808 ).

Yesterday, I decided to update that kernel (from 6.3.9-lp154.2.1.g0df701d to 6.4.0-lp154.2.1.gd68cda5). To do this:
I enabled the repo
I used Yast software management
I told it to install the newer kernel and remove the older one
I then disabled the repo once again

On reboot, I got a MokManager blue screen wanting to remove the cert that had been added for the older kernel.  This seems a mistake, since it is still needed for the newer kernel.

As best I can tell, Yast first removed the older kernel and that generated a request to remove the cert.  It then installed the newer kernel, but because the cert was already loaded it did not generate a request to add the cert.

(When I next update this kernel, I'll make sure to install the new kernel first, and then remove the old kernel afterwards to avoid this issue).

Yes, I could have left it to the purge-kernels service to remove the old.  But that would have instead removed the standard Leap 15.5 kernel, and I wanted to avoid that.

Reproducible: Didn't try
