Is there a special method to upgrade from 12.04 to 14.04?
When I try to upgrade from 12.04 using update-manager -d
I receive the following error message:
fetching upgrade failed.
There may be a problem with the server.
Am I missing any steps?
Does anybody have a solution for this?
Followed guidance on ubuntu website for upgrading to 14.04. I read it to say that each release after 12.04 had to be installed subsequent to installing next release to finally get 14.04 installed. Did not understand that un-supported releases are moved to a different server and are essentially unusable, hence the error message that I received.

This is a summary of what I've found. We've no idea what you've tried so far as troubleshooting so don't get upset if this is something you've already attempted.
sudo gedit /etc/apt/sources.list
. Replace the contents with your newly generated sources list.sudo apt-get update && sudo apt-get upgrade -y && update-manager -d
