Just updated Ubuntu 20.04, restarted the computer and my Wifi adapter went MIA in the process:
Settings > Wi-Fi
No Wi-Fi Adapter Found
That’s OK. I can run this magical command and everything should work fine:
sudo apt-get install --reinstall bcmwl-kernel-source
But, I get these series of errors:
Loading new bcmwl-220.127.116.111+bdcom DKMS files... Building for 5.8.0-34-generic Building for architecture x86_64 Building initial module for 5.8.0-34-generic ERROR: Cannot create report: (Errno 17) File exists: '/var/crash/bcmwl-kernel-source.0.crash' Error!

What do I do to get my wifi adapter back? Bonus points if you can explain what happened.
