networking – How can I fix Broadcom driver Wifi with 5.8.0-xx kernel on Ubuntu 20.04

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- 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! Bad return status for module build on kernel: 5.8.0-34-generic (x86_64)

Errors were encountered while processing:
E: Sub-process /usr/bin/dpkg returned an error code (1)

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