Failed retrieving file 'endeavouros.db' from github.com - Resolved

This problem has cropped up again for me. I’m using the endeavouros-2019.12.22-x86_64.iso with an offline install. Installation goes great but as soon as I try to run an update I get the error message:

error: failed retrieving file ‘endeavouros.db’ from [github.com](http://github.com/) : Resolving timed out after 10000 milliseconds

What is necessary to get it updating?
