Bug Description


Currently the DKMS package fails to install on supported custom
kernels that are based on 4.15. That includes the current 4.15
hwe-edge and some of the custom and cloud kernels as well.

[Test Case]

Install the broadcom-sta package with the 4.15 hwe-edge
kernel. The package installation should proceed without any

[Regression Potential]

Although new patches were added, the regression risk is very low since the new
changes are conditionally compiled based on the kernel version.

Besides that, the new package was tested with the following kernels in an amd64

- linux-generic 4.4
- linux-hwe 4.13
- linux-hwe-edge 4.15
- linux-azure 4.15

Hello Everybody!

Can anyone tell me please "Step by Step" how to install the patch or package?

I do not have a clue how to do it as I am not an IT expert and I am a new Ubuntu 16.04 user, but still need to solve this wifi issue!

Thank You So Much!

I am a newbie too. Sorry -- didn't take notes :(

The main steps that I used were:

Removed the existing driver: sudo apt-get purge bcmwl-kernel-source

Enabled proposed archive: To enable the proposed archive for Ubuntu 16.04 and later use the Software & Updates program and ensure that Pre-released updates (xenial-proposed) is ticked in the Developer Options tab. (Source:

Install: sudo apt-get install broadcom-sta-dkms/xenial-proposed (Source: Stan's comment above for the package name)
