Ubuntu-release-upgrader can not calculate the upgrade to 20.04

[Matthew Schmerer]

The release-upgrader can not calculate the upgrade after removal of the hauppauge kernel drivers. I have some other ppas installed, but those haven't caused problems on upgrade in the past.

Any assistance you all can provide would be helpful. Thanks!
