You haven't responded to my earlier post suggesting to you to start
afresh: format your HD and install whatever version of openSUSE you
have -- I think you are able to install 42.3. Do that and then after
you have this running we can go then walk you thru on how to install
the latest, new, kernel. OK?


I have ordered a new  PCIe NVMe - M.2 Internal SSD to build a new system
on. No std hard drives in this system. The SSD is not due to arrive for
a week or so. I would be anxious to try the walk thru you suggest at
that time.
I am not against the RPM database concept. I just did not realize it was
used to keep track of installed versions etc. I once asked on this list
for documentation describing the system architecture and did not receive
any relevant responses. RPM originally stood for Red Hat Package
Manager. I started under Red Hat and did not realize RPM was critical to
opensuse. I would gladly have used the rpm --erase if I had known it was
relevant. It is certainly easier than deleting all of the files  in
/boot and repairing the links.

Contrary to Windows, an RPM based Linux system keeps track of what is
installed in a database. On Windows, to install something, it is simply
installed on top of what exists already, overwriting it if it happens to
use the same directory, or otherwise having the same thing installed on
several different paths, known only to the applications that use them.

Thus to repair things, you re-install.

On Linux, when you tell YaST to install/update/remove something, it
_thinks_. What is already installed, what is needed to do to obtain what
the user is requesting. And to do so it queries the database of
installed packages, and updates it with the changes. Every single file
that was installed from a package is listed there (exceptions are files
created locally by installation scripts).

Thus if you delete a file manually YaST/zypper/rpm will think that the
file is still there and the decisions it takes will be based on that
knowledge, that happens to be wrong because you deleted something.

If you *only* deleted some files in /boot, consequences are probably not
that important. Maybe. Just remove the packages that had them and issue

But if you are in the habit of deleting installed files, things get
