how do I download 10.15 to upgrade 10.10

I can't access a link to download 10.15 through app store. It doesn't appear. Using Macbook pro mid 2012.

How can I reset the app store so that catalina shows up on list?

Choose Applications from the Finder's Go menu, throw away the existing installer, and download a new one. If you continue to get that message, restart with the Shift key held down, and if possible, use a wired Internet connection.


Opening the link in Firefox will produce a different error message or just be ignored.
