Problem installing Broadcom WiFi driver Zorin 18

[canoehull]

I'm trying to install a WiFi driver on my new installation of Zorin OS 18 Core but get error messages.

Additional drivers:

Error message:

I am able to install the drivers on this same computer running LimeOS.

Any suggestions? Thanks, Doug

In terminal, can you please show the verbose output of

sudo apt install broadcom-sta-dkms

I bet it will complain about the 6.x kernel...

[canoehull]

This is the output from the command with -v:

doug@doug-MacBookPro:~$ sudo apt install broadcom-sta-dkms -v
apt 2.8.3 (amd64)

This is the output without the -v (verbose):

doug@doug-MacBookPro:~$ sudo apt install broadcom-sta-dkms

Now I'll reboot to see if WiFi appears...

After rebooting still no WiFi.

What is your terminal output for

lspci -nnk | grep -A3 -i network

I think I've got it working. I found this article on AskUnbuntu and went through it step-by-step and works now. My particular laptop is a 2013 Macbook Pro now repurposed to try out various Linux distros. I'm glad we solved the problem; this is my favourite so far.
Thanks, Doug

Wow.

We were focusing only on the broadcom-sta driver, because that is what the system reported... we did not think to try firmware-b43-installer...
