Hello. I have a macbookpro2012 that I am running ZorinOS 17.3Pro as my daily driver. I re-installed Zorin on laptop after not being able to resolve getting access to my server via DNS. With the re-installation, that got fixed, but now my wifi-adpater is missing. I can only get internet if I am hardwired. I tried re-installing it again but to no avail.
~$ sudo apt install broadcom-sta-dkms=6.30.223.271-23ubuntu1.2

Package broadcom-sta-dkms is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Version '6.30.223.271-23ubuntu1.2' for 'broadcom-sta-dkms' was not found
Do you know what might have happened to change this from working to not working when I have been using the same computer and the same ZorinOS installation file?
