In Ubuntu we recommend to only install broadcom-sta-dkms.
It ships modprobe.d snippet that does prevent automatic loading of b43 driver.
# cat /etc/modprobe.d/broadcom-sta-dkms.conf
# wl module from Broadcom conflicts with the following modules:
blacklist b43
blacklist b43legacy
blacklist b44
blacklist bcma
blacklist brcm80211
blacklist brcmsmac
blacklist ssb
broadcom-sta-source doesn't do anything but does reocmmend module-
assistant, if one uses that it probably is best to switch to the dkms
package. Separately broadcom-sta-common is provided that could be
installed together with boradcom-sta-source to also gain the blacklist
modprobe.d. Not quite sure what is the point there, maybe we can make
broadcom-sta-source depends on broadcom-sta-common, or simply remove it.
My expectation was that this is all solved already back in lunar =/
Shall I ship modprobe.d snippet in more places? and have initramfs hook
to ensure initramfs is regenerated with updated modprobe.d? What's wrong
with the gui that seems to not show things correctly?

Bug description:
Specifically for Lunar - using a Macbook Air 2012, its wireless driver
was not enabled even though I ticked the wireless tickbox on the
installer.
A quick look at the installer logs reveals various issues

I will attach the installer logs manually since this was captured
after the installation
Note - on 20.04.6, 22.04.2 and 22.10 with the same laptop bcmwl was
installed correctly during the install so this is a regression with
the 6.2 kernel
Workaround
----------
You'll first need to blacklist the b43 driver by adding a blacklist file to
/etc/modprobe.d/b43.conf with the contents "blacklist b43". Then run
"update-initramfs -u". Then install the bcmwl-kernel-source package. After a
reboot your wireless device should be available.
