Yes, I agree this does look like a duplicate of Bug #1910555. I'm not sure why I didn't see that one when I was looking for bugs that corresponded to my problem.
Anyway, this solution worked for me: 1. Manually download the bcmwl-kernel-source package from this page: https://packages.ubuntu.com/groovy/bcmwl-kernel-source Make sure that you get the "6.30.223.271+bdcom-0ubuntu7" version from the "groovy" repository, not the older version from the "focal" repository. (You might also need to install or reinstall the "dkms" package, which you will see a link to under "related packages".) (I needed to download the package on a different computer and transfer on a flash drive it to the laptop where the wifi wasn't working because that laptop doesn't have an ethernet port.) 2. Open a terminal, go to the directory where the package file is located and run dpkg with this command: sudo dpkg -i bcmwl-kernel- source_6.30.223.271+bdcom-0ubuntu7_amd64.deb 3. Enter your administrator password. The broadcom driver kernel module should install automatically. If you get an error saying that package you are trying to install depends upon some other package that isn't available, download that package from packages.ubuntu.com and install it using the command: sudo dpkg -i [package file name], then try step 2 again. For me the installation worked fine, and the wifi came back on instantly and even automatically reconnected to my home network. I didn't even need to reboot! So this is definitely an effective workaround, but this bug won't really be solved until Canonical gets this patch into the focal repositories. (And even then, people will still have to manually reinstall their wifi driver if they don't have wired internet access.) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1910875 Title: Broadcom wireless driver failed to install with code 10 on focal 20.04 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1910875/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
