@Sami: the compilation is done automatically by the installer. You can either plug in Ethernet or reboot and chose Advanced Ubuntu boot option, scroll down to the previous ver. of the Kernel (4.13) and boot with it normally to get the WiFi connection back. Then "See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed" - just a couple of steps that don't affect your overall system if you "Create the file /etc/apt/preferences.d /proposed-updates with this content:...". Then sudo apt-get update and sudo apt-get install broadcom-sta-dkms/xenial-proposed. This should successfully compile for both 4.13 and 4.15 kernels. Then reboot normally and forget about this incident till the kernel testing flow breaks again next year or whenever.
