  Upgrade via re-install process.

  Error I see:

  Background:

  This was a 18.04/bionic install; though I've tried to install Lubuntu
  focal daily on it twice (errors twice) so this could reveal extra
  detail as to what the issue is, or be a consequence of something
  else...   Either way I'll look and hopefully learn more soon.

  May 18 06:03:42 kubuntu /plugininstall.py: Could not restore packages from the previous install:

  NOTE:  if this issue is just the restoration of prior packages, it's
  NOT A CONCERN, as I may very well have had python2, Qt4 & other no
  deprecated software & the error message telling me all packages could
  not be installed is not surprising.  This box is old; /home will
  contain data from late-GTK2 days (ubuntu 11.04 era upgraded & re-used
  like I did today)
