Comment 24 for bug 1676547

I am truly sorry to say that I have tried many of the recommended solutions for this problem but to no avail. I am running Ubuntu 16.04 on a AMD 8-core desktop machine and if I ever ever ever even try to give a command like sudo apt-get update and apt-get upgrade I inevitably find myself with an operating system without ethernet connection. I have been unable to fix that no matter what I have tried so far. I have spent DAYS reading the blogs and trying to get a fix for this bug. In the end the only solution I could find so far was to use the original ssd back up disk to get back to the original system, before the sudo apt-get update etc commands. Can anyone in this forum or elsewhere explain in a simple and clear manner how to fix this major issue with ubuntu upgrades?
