Title:
  software-properties-gtk fails to launch via "Additional Drivers" or
  via terminal

Status in software-properties package in Ubuntu:
  Incomplete

Bug description:
  Issue present since reinstall of Ubuntu. Originally thought similar to
  (https://askubuntu.com/questions/789966/software-updates-crashes-and-
  will-not-open) but solutions did not work, even though terminal output
  (https://pastebin.com/FpD1MFC3) is highly similar.

  I have tested using a new user and the issue remains.

  1)
  Description:	Ubuntu 19.10
  Release:	19.10
  Linux version 5.3.0-26-generic (buildd at lgw01-amd64-013) (gcc version 9.2.1 20191008 (Ubuntu 9.2.1-9ubuntu2))
  2)
  software-properties-gtk:
    Installed: 0.98.5
    Candidate: 0.98.5
    Version table:
   *** 0.98.5 500
          500 http://gb.archive.ubuntu.com/ubuntu eoan/main amd64 Packages
          500 http://gb.archive.ubuntu.com/ubuntu eoan/main i386 Packages
          100 /var/lib/dpkg/status
  3)
  Additional Drivers utility should launch when executing command "software-properties-gtk" with or without root.
  4)
  Long error fight between dbus and python3.

  A note on attempted solutions. Reinstalling dbus/dbus-x11 and
  following the noted askubuntu thread did not help.
