[Bug 1687623] Re: linux-4.4.0-77.98 was a phased update in -updates only and may become partially installed (was: 4.4.0-77-generic breaks internet on 16.04.2)

[Stephen Cheong]

Also encountered very similar problem.

I'm using Acer Aspire V7 laptop with Ubuntu 16.04 LTS. An update popped
up, but I wasn't quite aware of what the update was about.

Restarted my computer, and then both wifi and ethernet connections
stopped working. The situation matches with the bug description. "Enable
Networking" checked, but no "Enable Wi-Fi".

Both wireless and ethernet cards were detected, but no kernel modules
seemed to be in use.

Also, screen brightness could not be changed. The Logitech wireless
mouse and the laptop touch screen stopped working.

Same as what's mentioned, no such problems if after reverting to
4.4.0-75-generic.

Bug description:
  Hi as per title today I updated to  4.4.0-77-generic on my Lubuntu
  16.04.02 and wifi is not working anymore. When I click on the network
  manager I see "enable networking" (which is toggled) but no more the
  option about wifi.

  I reported this on ubuntuforum:
  https://ubuntuforums.org/showthread.php?t=2360216

  Where a user suggested to revert to an older kernel and see if this
  fixes the problem. I managed to revert to 4.4.0-75-generic via grub
  and everything works perfectly.

  Another user reported a similar issue caused by the same upgrade on
  the same system: https://ubuntuforums.org/showthread.php?t=2360215

  Can someone else confirm this bug?

  If you need more information I will be happy to provide it (I am a
  newbie though so please be patient).
