I'm having no luck upgrading my Ubuntu 18.04 to 20.04. At every attempt, the upgrade process is interrupted with this message:

What do I do?

You don't seem to have any bionic-updates sources, nor any bionic-security sources. Those are required for a properly-functioning Ubuntu system.

That is the most likely cause of your current problem. Turn those back on, install the mountain of updates thence, and then try your release-upgrade again.

Those sources don't get turned off automatically. A human did that.

The lack of security updates may be a serious problem: Were you on my network, you would be required to do a full wipe-and-reinstall. If you don't recall how or why those sources were disabled, then a reinstall might be a very good idea.
