Hello Aaron,
Actually during upgrades, the system first attempts to download the packages. You can see that on the 6th screenshot. “Getting packages”. If this step fails, the system will automatically revert any changes. In case the networking stops after this step, the upgrade will proceed in offline mode as all the required packages are already downloaded on your computer.
i mentioned that because i tried upgrading Ubuntu 14.04 to 15.04 from terminal and i had a network break down and after restarting my machine, the DE was not loading.After searching for solutions, of which i did not get one, I had to do a fresh install of Ubuntu 14.04.
I have one concern with upgrades though, won’t it affect your system in case network goes down?
it will not, it will just be interrupted.
if the power goes down you will have problems…. so make sure if its a laptop. you battery is fully charged
