I encourage flavours using Qt to fix this if they care about it.

Title:
  "Apply changes" button remains disabled after selecting Wi-Fi driver
  in Software Sources

Status in software-properties package in Ubuntu:
  Triaged

Bug description:
  I'm testing the live USB of Ubuntu Studio 22.04 beta on a mid-2009
  MacBook Pro. (Can't do a full install yet.) Wi-Fi doesn't work out of
  the box.

  What I expect to happen is something I can do successfully in Ubuntu
  Studio 21.10 (live USB). Wi-Fi also didn't work out of the box in that
  version. In KDE Settings I click on "Driver Manager", which
  automatically opens Software Sources (that's the only way I know how
  to get there). It finds and shows my [proprietary Broadcom] Wi-Fi
  driver; I click on it, then the "Apply Changes" button is enabled
  after a second or two. I click that, wait about half a minute with a
  progress bar in action below, and then the Wi-Fi options appear the
  notification area, allowing me to connect.

  I attached a screen record of what actually happens in Ubuntu Studio
  22.04 beta (thankfully this distro comes with screen recording
  software out of the box). When I click on "Driver Manager", a "xterm"
  window (version 372-1ubuntu1 I think?) opens unexpectedly with some
  code showing up in it (the code is in the screen record), shortly
  before Software Sources (version 0.99.20) opens as expected. The same
  driver still appears on the list. When I click on the driver, it seems
  to still take that second or two to transition, with some more code
  appearing in "xterm", but the "Apply Changes" button never enables
  itself. It remains disabled so I can't click it. The "revert" button
  directly next to it is also disabled. Thus, I can't connect my
  computer to Wi-Fi in 22.04 beta.
