UPGRADE STEPS FOR UBUNTU 16.04--
After a quick web search, I pulled up the following steps:
Steps to upgrade Ubuntu 16.04 to 18.04
1) Login to Ubuntu box.
2) Patch current system by running sudo apt update && sudo apt upgrade.
3) After reboot make sure either UFW firewall is temporarily disabled or TCP port 1022 is open.
4) To upgrade Ubuntu 18.04 LTS from 16.04 LTS run sudo do-release-upgrade.
I'll try this and report my results. --scryptr
Quick answer: upon updating, upgrading, and rebooting, I issued "sudo do-release-upgrade". The message in return was "no upgrade found".
What do you suggest? Is there a setting that I need to change? --scryptr
Updates are usually disabled in nvOC,
So you need to open up "Software & Updates"
Check mark the updates in "Ubuntu Software" section and also in "Updates" section check mark them all
Also in "Updates" section , the last part is "Notify me of a new Ubuntu version" select "For long term support version"
When you click close it will reload and should notify of new release
