I downloaded the new install image:
  openSUSE-Leap-15.3-2-DVD-x86_64-Build20.8-Media.iso
I then did an install using that image.

The install went well.  But, on attempting to update, there was a conflict:

Problem: the installed product:Leap-15.3-2.x86_64 requires 'product(Leap) =
15.3-2', but this requirement cannot be provided
 Solution 1: Following actions will be done:
  do not install patch:openSUSE-2021-820-1.noarch
  do not install patch:openSUSE-2021-863-1.noarch
 Solution 2: downgrade of product:Leap-15.3-2.x86_64 to
product:Leap-15.3-1.x86_64
 Solution 3: break product:Leap-15.3-2.x86_64 by ignoring some of its
dependencies

It looks as if something is missing.

In the meantime, trying to update a previously installed 15.3, I see:

The following product update will NOT be installed:
  openSUSE Leap 15.3  15.3-2
Nothing to do.

That's part of the output from "zypper -v up".  It appears to be describing the
same problem.

I have set the component to "Installation", although the installation itself
went well.  But that seems the closest fit for now.

Reproducible: Always
