Upgrade to Version 10.15
How do I upgrade from a 10.13.6 version on a Mac mini to a 10.15 version? I've tried several times to upgrade and I get an error message saying "unable to download" because I am operating on a 10.13 version.

Whether you can update or not, depends on the exact model of Mac you have, not the macOS version it is running.
Also, where are you trying to download the update from exactly?
If you have a compatible Mac, see here to download Catalina: link-> How to get old versions of macOS - Apple Support
