Thank you for taking the time to report this bug and helping to make
Ubuntu better.

Bug reporting is mostly about finding & fixing problems thus preventing
future users from hitting the same bug.

I suspect a Support site would be more appropriate, eg.
https://answers.launchpad.net/ubuntu. You can also find help with your
problem in the support forum of your local Ubuntu community
http://loco.ubuntu.com/ or asking at https://askubuntu.com or
https://ubuntuforums.org, or for more support options please look at
https://discourse.ubuntu.com/t/community-support/709

fyi: https://packages.ubuntu.com/bionic/ppa-purge

Bug description:
  At first, it reported possible problem with PPA, so I searched for
  information about the ppa's and found references to ppa-purge, which
  is not an installable app, after I tried sudo apt-get install ppa-
  purge   or ppapurge.  Then I found an article that showed up to get to
  the ppa list in the software updater tool.  I did so;  it sill cannot
  calculate the upgrade.

  I run about 6 different computers.  This computer is a back up
  computer, running Ubuntu 18:04 and I'm trying to upgrdae to 20:04.
  On my main Linux computer, I'm running Pop!_OS.  I have Ubuntu studio
  on the computer I use for my radio show (www.baroqueandbeyondradio.com
  or more simply bnbradio.com), and then have Microsuck Windows on a
  desktop and laptop to connect to work via required VPN.

  So, updating this computer is not urgent, but I would like to finish
  an update.
