Broadcom Wireless Drivers do not install properly as of Ubuntu 22.04

[Ben Randall]

When installing Broadcom Wireless driver (bcmwl-kernel-source) the package does not properly force the updating of the kernel module blacklist, and as a result the system still loads a conflicting driver (bcma). Users need to manually call the command:

   sudo update-initramfs -u

Which correctly updates the blacklist allowing the Wireless adapter driver to load. On ubuntu versions 20.04 and earlier, installing the driver allows the network card to work immediately (no reboot require, it even works on the USB live distro). For version 22 and 23, it's possible to get it working by manually removing the b43 and bcma drivers, and then adding the wl driver, or running the above command.

I'm filing this bug at the suggestion of an Ubuntu member who suggested that the bcmwl-kernel-source package should probably already be performing the update-initramfs command as part of it's installation.
