[Bug 1821823] Re: No wireless networks displayed for broadcom BCM43142

[Łukasz Zemczak]

Weird, looks like during shim-signed installation, when the bcmwl dkms
module is uninstalled to be signed, a check for the dkms status fails
expectations. For some reasons shim-signed expects the uninstalled
module to return status 'built' (which it does on my cosmic system
here), but on disco this seems to result in something else. It feels to
me that the behavior of dkms changed between cosmic and disco and now
either dkms uninstall removes the module completely (not resulting in
being 'built' after the uninstall) or maybe dkms reports the status
wrongly (differently).

Title:
  No wireless networks displayed for broadcom BCM43142

Status in ubiquity package in Ubuntu:
  New

Bug description:
  For 19.04 UB did a minimal install.  I selected the ubiquity
  proprietary option and expected the broadcom driver to be found and
  installed.

  On reboot I could not see any wireless networks.  I went to the
  Additional Drivers window and it stated that the computer was indeed
  using Broadcom 802.11 Linux STA wireless driver and was in use.

  This is a regression - in both 18.04 and 18.10, the same steps also
  installed the driver, and wireless networks were found and could be
  connected to.
