Title:
  Proprietary Wi-Fi drivers fail to install if you go back and enable
  the downloading of updates during Ubuntu installation

Status in ubiquity package in Ubuntu:
  Incomplete

Bug description:
  Bug discovered doing RC ISO testing for Ubuntu 20.04.5.

  Hardware is an HP Elitebook 8570p, 16 GB RAM, 120 GB SSD, UEFI, no
  secure boot, **with a Broadcom Wi-Fi module**. You will probably need
  a system with a Broadcom Wi-Fi module (or possibly some other hardware
  with proprietary drivers like an NVidia card) in order to reproduce
  this issue.

  Steps to reproduce:

  1: Boot an Ubuntu Desktop ISO.
  2: When offered to either try or install Ubuntu, click "Try Ubuntu".
  3: Launch Ubiquity.
  4: Proceed through the installer accepting the defaults until you get to the 'Updates and other software' screen.
  5: Check the box to install proprietary drivers, and proceed to the next screen. Your Wi-Fi should start working.
  6: Go back to the previous screen.
  7: Connect to Wi-Fi.
  8: Once connected, check the box to download updates while installing Ubuntu, then proceed to the next screen.
  9: Finish the rest of the installation (using the "Erase Disk and install Ubuntu" option), then reboot when finished.

  Expected result: The system's Wi-Fi should be fully functional when
  the newly installed OS boots.

  Actual result: The system cannot see any Wi-Fi networks. Running
  "dpkg-query -s bcmwl-kernel-source" reveals that the Broadcom Wi-Fi
  drivers are not installed.


  Notes:

  If you skip steps 6-8 (don't go back to the previous screen to enable
  downloading updates during installation), the Wi-Fi will work in the
  newly installed system. For some reason the problem seems to trigger
  if you go back to enable downloading updates.

  This problem occurs on Ubuntu Studio 20.04.5, as well as Ubuntu
  Desktop 20.04.5.

  Logs will be attached later, this bug is so I can report the failure.
