I'm also on 20.04 and my network connection stopped working after an update today. I have a Broadcom BCM4360.
I got things working again by following the steps shared by rafae-s (thank you!), but I expect that other 20.04 users will come across the same problem in the next couple of days. Does a fix for 20.04 also need to be released? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1878045 Title: doing dist-upgrade got error related do Broadcom Status in bcmwl package in Ubuntu: Fix Released Bug description: I had a working 20.04 installation running, including the Broadcom Wifi.
