How to Reflash a Ubiquiti UniFi Security Gateway (USG)

A few weeks back we had a power outage at our home. Electricity was restored a few hours later and we all thought nothing of it. Everything turned back on and my home network seemed to function correctly.

About a week later, I logged in to my Ubiquiti Network Manager Controller and saw that my Ubiquiti UniFi Security Gateway (USG) was no longer sending over data to the controller software. I still thought little of this issue, since the USG was still routing and blocking unsolicited traffic.

3… 2… 1… Failure to Launch

In 2017 I was one-half of a small startup, here in Louisiana. A a new startup, we were going to join the ranks of companies that were ready to dream and create the Internet of Things (IoT) industry. At the time, smart mirrors were still homemade projects which relied on multidisciplinary hobbyists that understood framing, technology, and software engineering.

They had some participants play a well-known card game with a full understanding of the rules, while they had other participants play an unfamiliar card game where the researchers did not define the rules. The second group was left to figure out the card game as they played.

Upgrading Ubuntu from 17.04 to 17.10

In June of 2017 I upgraded my Ubuntu 16.10 (Yakkety Yak) LTS install to Ubuntu 17.04 (Zesty Zapus). In October of 2017 Ubuntu released 17.10. (Artful Aardvark). I had not needed to upgrade my Ubuntu 17.04 installation for a while, but I felt it was best to keep it up-to-date. I was also experiencing issues with it from day-to-day. I decided an upgrade might work to fix some of the issues I was having.
