Title:
Broadcom wireless driver failed to install with code 10 on focal
20.04
Status in bcmwl package in Ubuntu:
Confirmed
Bug description:
First, I suspect this may be the same bug as Bug #1905211 "package
bcmwl-kernel-source 6.30.223.271+bdcom-0ubuntu5 failed focal fossa in
kernel v5.9" because I got the same error "installed bcmwl-kernel-
source package post-installation script subprocess returned error exit
status 10". However, I wanted to make a separate report because I am
still on kernel v5.8. Please merge these threads if it seems like
they're the same bug.
Anyway, my problem is this:
The last time I installed a tranche of system updates, I got a "System
software problem detected" dialog and submitted the crash report. The
next time I booted up my computer, the Broadcom wifi device was not
recognized. The wifi had worked fine up until that point.
I tried to manually uninstall and reinstall the driver using dpkg with
the bcmwl-kernel-source (6.30.223.271+bdcom-0ubuntu5) package
downloaded from packages.ubuntu.com (the machine in question does not
have a wired ethernet connection). dpkg produced the following
output:
