The Remotes For My Craftsman Garage Door Opener Have Stopped Working. I Followed
the procedure for Erase All Remote Codes and it worked as listed. Then I follwed the procedure for To Add a Remote Control. 1) Press and hold remote button; 2) Press and release the learn button. **A result was that the indicator light came on, stayed on for perhaps 20-30 seconds and then went off; 3) Wait for the opener light to flash **it never did; 4) Release the remote button. The remote still doesn't work. Where am I going wrong?

You are doing it right and have the right understanding of how it works. The opener light only blink and/or click click from the opener to let you know it learned the code from your remote.
Replace the battery in the remote and try again.
Try another remote with a fresh battery and/or the keypad
If that not working, you might have a bad logi board. You can have some that interfere with the signal from your remotes.
