[Bug 1993370] [NEW] Cannot install proprietary Broadcom WiFi drivers on Ubuntu Studio Kinetic

[Aaron Rainbolt]

Public bug reported:

Hardware: HP Elitebook 8570p, 16 GB RAM, 120 GB SSD, 3rd Gen Intel Core
i5, UEFI, no secure boot, Broadcom WiFi.

OS: Ubuntu Studio Kinetic, Final ISO

Steps to reproduce:

1. Boot the Ubuntu Studio ISO on a system with Broadcom WiFi, and install the system normally. (No encryption, allow Internet access during installation using some method of connectivity other than WiFi.)
2. Reboot and log into the newly installed system.
3. Open a terminal and run "sudo software-properties-kde".
4. Click "Additional Drivers" in the window that pops up.
5. Click "Using Broadcom 802.11 Linux STA wireless driver source from bcmwl-kernel-source (proprietary)".

Expected result: The Apply Changes button should become clickable,
allowing the user to install the driver.

Actual result: The button remains grayed out, and the following error
message is printed in the terminal:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/softwareproperties/qt/SoftwarePropertiesQt.py", line 1063, in on_driver_selection_changed
    modules_package_obj = self.apt_cache[modules_package]
TypeError: Expected a string or a pair of strings
