What I saw was that VirtualBox was also corrupt in the 117 O/S but not in the 115 version. The solution above fixed the WiFi and VirtualBox.
Please note that I generally do not like using Discover to run updates. I prefer:
sudo apt update
sudo apt upgrade
Sometimes Discover locks updates from the command prompt, and I have to kill the locks. Discover takes a long time to do updates. I thought the "silent upgrade" was a new feature of Discover.
The "bot" upgrade was something new to me, and now I think that it might be a security problem.
Problem Solved: I fixed the issue with:
sudo apt-get install --reinstall linux-image- 4.15.0- 117-lowlatency 4.15.0- 117-lowlatency 4.15.0- 117-generic
sudo apt-get install --reinstall linux-headers-
sudo apt-get install --reinstall linux-image-
