[Bug 1899678] Re: No wifi after installation - does not work with secure boot enabled

[fossfreedom]

The full terminal session is in modprobe.txt but in summary the bcmwl-
kernel-source reinstall was simply:

    apt --reinstall install bcmwl-kernel-source

This is a full ISO installation - no extra packages added/nor removed

modinfo wl returns a sig_key signature

The output of the mokutil sed is

Title:
  No wifi after installation - does not work with secure boot enabled

Bug description:
  After installation I noted that my broadcom wifi was not available.
  This is a regression from 20.04 where installation automatically
  installed the broadcom driver.

  So I tried to force the installation again - see trace below.

  The dialog message to enter the secure password appeared - however on
  reboot a confirmation to change the MOK state was not seen - the
  distro booted straight in.

  sudo apt install --reinstall bcmwl-kernel-source
