This may be useful for testing both the upgrade process and the features of 16.04 itself in advance of the official release date.

I've been trying to upgrade my installation of Ubuntu 9.04 to 9.10, but all of the instructions I've found haven't been helping.

check /etc/apt/and /etc/apt.d/* Maybe the upgrade documentation does help you. Edit: This guide does also have a new method using the console..that doesn't work I'm out of ideas, sorry: @taspeotis: I'm not totally sure if you just 'don't know it better' or just try to troll.

Recompiling the kernel in Ubuntu won't fix anything, especially since Ubuntu isn't a Source-Distro.

(for the Run App window) then type "update-manager -d".

The Ubuntu operating system's next Long Term Support release, version 16.04 (Xenial Xerus), is due to be released on April 21, 2016.

Although it hasn't yet been released at the time of this writing, it's already possible to upgrade a 15.10 system to the development version of 16.04.

Would you like to answer one of these unanswered questions instead?

I assumed it was just a keyboard shortcut to Update Manager and I could do that just as easily using System | Administration | Update Manager.

But that Thank you for your interest in this question.
