12.04 LTS to 14.04 LTS Server upgrade failing

"Am I missing something simple?"
What shows terminal command:
grep Prompt= /etc/update-manager/release-upgrades
That should show Prompt=lts if the settings are correct.

Maybe Yes, maybe not so yes

/etc/update-manager/release-upgrades file contains:
[DEFAULT]
Prompt=lts

I even tried changing to "normal" and running.

I attempted with the -c and no classification with the same result "no new release found". I'm running from terminal - attempted locally at console.

-d is for the development version which is 17.04.

Throwing random commands at systems will break your system. The interpretater does what you say. There is no checking so you have to be the smart one. Be careful

What is the output of:

sudo apt-get update

Thanks

(1/2) - Yeah
(2/2) - Both apt-get update and upgrade both ran as well as dist-upgrade; however, I backed it back down a package version as I had read a bug report of the linux-headers-generic-lts-trusty Linux-image-generic-lts-trusty possibly causing issues with the upgrade. So the two trusty packages are the only two not upgraded (held back).

What is the output of the commands

uname -a
lsb_release -crid
sudo apt-get update
sudo apt-get dist-upgrade

(1/4) Linux 3.13.0-116-generic #163~precise1-Ubuntu SMP x86_64 GNU/Linux
(2/4) Distributor Id: Ubuntu Description: Ubuntu 12.04.5 LTS Release: 12.04 Codename: Precise
(3/4) Ran without problems (also ran apt-get upgrade without problems)
(4/4) Updated the kernel to 3.13.0-116 (I've tried to upgrade with both 115 and 116 Trusty kernels)

I've also run:

sudo apt-get install -f
sudo dpkg --configure -a

to check for any broken dependencies. Everything seems fine. I have read where the sources.list file can be manually edited to Trusty DEB pointers, but this may cause system issues, any further ideas?

Please provide the output of the commands, not your own interpretation.

I was also wondering if anyone has tried updating server via .ISO (CD/DVD) route? such as in this thread;
https://help.ubuntu.com/community/PreciseUpgrades

Try the command

sudo do-release-upgrade -p

If this still fails, please upload the files /var/log/dist-upgrade/main.log and /var/log/dist-upgrade/apt.log to pastebin.ubuntu.com and provide the links that you get in a new message of this question thread.
