I have read through multiple articles giving instruction on how to go from 16.04 to 18.*. None of which appear to be working for me.
When I get to
I get the message
Checking for a new Ubuntu release Please install all available updates for your release before upgrading.
Currently I have /etc/update-manager/release-upgrades set to normal Setting this to LTS yields the same results.
Additionally this is after running both:
sudo apt update && sudo apt upgrade
Of course if I run
I get the message
Upgrades to the development release are only available from the latest supported release.
This makes sense to me. What am I missing here? Can I go from Ubuntu Server 16.04 to 18.*?
I noticed now when I run
sudo apt update
I get this output

I believe this may be whats keeping me from upgrading to 18.*. I am a little stuck at this point.
Was able to get this resolved with the answer that I accepted.
I also had to clean up some repos that were dead. I ran into an issue where I could not connect to security.ubuntu.com as well. To resolve this I did the following:
sudo vi /etc/gai.conf
Uncomment the following line
# # For sites which prefer IPv4 connections change the last line to # precedence ::ffff:0:0/96 100
I was able to finish updating. Now upgrading my distro of Ubuntu
