bcmwl-kernel-source broken on kernel: 5.8.0-34-generic
15,595
Solution 1
The reason is obvious. Almost every time Canonical rolls out a HWE kernel, they forget to upgrade bcmwl-kernel-source in the repos.
You have two solutions (use one or the other, it makes no sense to use both):
- Install
bcmwl-kernel-sourcefromgroovyrepos. You can find it e.g. here. http://mirrors.kernel.org/ubuntu/pool/restricted/b/bcmwl/bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu7_amd64.deb It will compile with the 5.8 kernel.
Download the deb and install it by
sudo dpkg -i bcmwl-kernel-source_6.30.223.271+bdcom-0ubuntu7_amd64.deb
-
Remove all 5.8 kernel packages using these commands:
sudo apt remove linux-{image,modules,modules-extra,headers}-5.8.0-36-generic linux-hwe-5.8-headers-5.8.0-36 sudo apt install linux-generic
Make sure that the linux-generic meta package is installed.
It is recommended to boot with the 5.4 kernel before you remove the 5.8.
The second solution will keep the 5.4 major kernel version with normal security upgrades.
Solution 2
I managed to restore WiFi with kernel 5.4.0-59-generic as follows:
- Purge all packages related to kernel
5.8.0-34-generic:sudo apt purge linux-image-5.8.0-34-generic linux-image-unsigned-5.8.0-34-generic linux-modules-5.8.0-34-generic linux-headers-5.8.0-34-generic - Purge the Broadcom WiFi driver:
sudo apt purge bcmwl-kernel-source - Remove redundant packages:
sudo apt autoremove - Put the
5.4.0-59-generickernel on hold:sudo apt-mark hold 5.4.0-59-generic - Update package metadata:
sudo apt update - Re-install the driver:
sudo apt install bcmwl-kernel-source
Since the 5.8.0-34-generic kernel is gone, the driver is compiled only for the 5.4.0-59-generic kernel which succeeds as expected. Reboot, and WiFi is restored.
Hopefully I can unhold the kernel and receive kernel updates as usual once this is sorted out.
Solution 3
Turns out, you can use the ubuntu 20.10 version of the package and it works just fine, at its origin repo
Solution 4
Broadcom Wifi crashed after Ubuntu 20.04 LTS kernel update 8.15.34 ~ 36
How to know kernel version?
uname -r
How to know your crashed adapter?
sudo lshw -C network
You will see the crashed adapter with the following title:
*-network UNCLAIMED
How to fix:
SOLUTION 1
Install the following device driver:
ALTERNATIVE
If not worked, try the following:
sudo apt-get purge bcmwl-kernel-source
sudo apt-get install bcmwl-kernel-source
ALTERNATIVE Reinstall the kernel
sudo apt install --reinstall linux-image-$(uname -r)
sudo apt install --reinstall linux-modules-$(uname -r)
sudo apt install --reinstall linux-modules-extra-$(uname -r)
After that try the above solutions again.
Solution 5
Found an alternative solution while tracing errors in bcmwl-kernel-source.
See this question on Unix & Linux SE
I tried the solution listed in the thread, which involves purging the bcmwl-kernel-source and installing broadcom-sta and it works for me in Ubuntu 20.04 LTS with the Linux 5.8.0-36 headers installed.
sudo apt-get purge bcmwl-kernel-source
sudo apt-get install broadcom-sta-source broadcom-sta-dkms broadcom-sta-common

Similar to bcmwl-kernel-source broken on kernel: 5.8.0-7630-generic except I'm using a standard kernel - WiFi worked without issues on my MacBook Air (2013) right until I pulled in the latest 20.04.2 update which included the
5.8.0-34-generickernel, and booting back into5.4.0-59-genericafterwards does not solve the issue. Anyway, details are as follows; any help would be much appreciated.lspci -vnn | grep Network03:00.0 Network controller [0280]: Broadcom Inc. and subsidiaries BCM4360 802.11ac Wireless Network Adapter [14e4:43a0] (rev 03) Subsystem: Apple Inc.

I followed Installing Broadcom Wireless Drivers and did the following:
-
lspci -nn -d 14e4:reveals that the PCI.ID is 14e4:43a0 (rev 03) so I should (re)installbcmwl-kernel-source sudo apt purge -y bcmwl-kernel-sourcesudo apt autoremovesudo apt updatesudo update-pciidssudo apt-get install -y bcmwl-kernel-source
... followed by a reboot.
I did all the steps (except the first one) with both the
5.8.0-34-genericand5.4.0-59-generickernels and the outputs for the last command are as follows:5.8.0-34-genericSTDOUT:

In the meantime, my Bluetooth is working so I am connecting to the Internet by Bluetooth tethering with my Android device. But it's very much a temporary solution and I would not like to rely on it for the long run.

Pilot6 over 3 yearsIt is not a good idea to put the5.4.0-59-genericon hold. It won't get updates. If you removedlinux-generic-hwe-20.04,linux-image-generic-hwe-20.04you'll never get the 5.8 again. But the 5.4 will get updates normally, e.g. to5.4.0-60. -
Donald Sebastian Leung over 3 yearsThanks, I followed the second solution you suggested and unheld kernel updates. As for the first solution, I don't need such a new kernel as long as everything works for me and my system is secure.
-
Pilot6 over 3 yearsI think adding the hwe meta was also a mistake by someone. They never came before till xx.04.2 releases. That will cause trouble for many people. But I am usng Ubuntu for a long time and expect some mess every beginning of an odd year ;-)
-
Pilot6 over 3 yearsInstall
synapticand remove all linux-image... and linux-headers... packages version 5.8 and also those meta packages. -
Hani over 3 yearsThank you! Option 1 worked a treat for me!
-
Pilot6 over 3 years
broadcom-sta-dkmsis enough. -
bmaupin over 3 yearsCould you also add a link to the upstream bug? While this is a great workaround, the proper fix needs to come from Canonical. Anyone affected by it should go to the bug report and mark that it affects them so it can get more attention: bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1910555

Anand Kulkarni about 3 yearsworked 100%. I tried the installation of deb package and driver worked and wifi also works 100% now and i did not have to downgrade to 5.4 version. My laptop is a little mini Lenovo ideapad S10-3 Model.
