I'm running Ubuntu 12.04 on EC2 and I want to upgrade to 14.04.
do-release-upgrade returns that there are no upgrades.
do-release-upgrade -d begins to work and then halts stating:
Calculating the changes
Could not calculate the upgrade
An unresolvable problem occurred while calculating the upgrade.
This can be caused by:
* Upgrading to a pre-release version of Ubuntu
* Running the current pre-release version of Ubuntu
* Unofficial software packages not provided by Ubuntu
If none of this applies, then please report this bug using the
command 'ubuntu-bug ubuntu-release-upgrader-core' in a terminal.

I've been searching for a couple hours and have yet to find the right way to ask this question to lead to an answer. Starting from scratch is not a simple thing as I've do a lot to this VM, it's actually a template for a fairly decently large army. Anyway, I'm not a n00b. Help would be very awesome.
