HELP: error some information was unavailable during an internal lookup(-69808)

I have a new 2019 Macbook Air. The computer froze up during my first attempt to install Catalina (first released version). Visited an Apple Store and the technician found it necessary to wipe the disk clean and reinstall Mojave. I was then able to restore my data from backup.

The next time I tried to install Catalina I used the release available online as of 10/23/2019. That installation failed with this error message:

MacOS could not be installed on your computer.

Some information was unavailable during an internal lookup. (-69808)

Quit the installer, restart your computer, and try again.

I did try again with the same results. Now back to running Mojave while awaiting a release from Apple that solves this problem.
