After a few hours of troubleshooting I was finally able to dual boot the latest version of Kubuntu (21.04) alongside Windows. Completely fresh install, nothing changed, tampered with, etc. However, there's no internet. It tries connecting for a while, but then fails with the error "No IP configuration available". After following tutorials and really not understanding what was going on I found out that ifap wasn't even installed. My best guess is that some linux kernel headers are missing as one guy said who had the exact same issue. I don't know which headers to install, or even how to at this point. I checked and I still have the network folder with some files in it, but the interfaces file itself was missing. I also have netplan since 18.04 and up use that as far as I know. Either way, I'm missing some interfaces and I have no idea what to do.
