I am working with Ubuntu servers since some month, so not too long. I never upgraded an ubuntu version. So right now I am running 12.04 and what I need is 13.04. I once hear that I should first upgrade to 12.10 and than to 13.04 (for me that doesn't make too much sense, but I am not sure).
When I run sudo do-release-upgrade -d
Ubuntu wants to install 14.04. As far as I know 13.04 is now the stable version. How to achieve the step by step upgrading? Even though it's not the best way, I want to try it out on my virtual machine.
