24.04 Pre release version - updates to Post release version?

[tomreid10]

Hi all - I'm running a pre-release version of Ubuntu 24.04. Now that the official release date has passed, I had expected to receive a software update to take my install from a pre release to a post release version.

I'm getting a "not all updates can be installed" message when I run Software Updater, so I'm getting concerned that I may not be able to properly upgrade to the post release version.

Can anyone help me understand if I can indeed upgrade to to the full post release version?

Clearly I can download a new version of 22.04 and run a fresh install - but Id rather not if I don't have to as there's lot of personal settings etc. I always install that I would have to re-do.

thanks

Please open a terminal.

Run "sudo apt update"
Then run "sudo apt upgrade"

Copy (not screenshot) the complete output of both. Paste the text into your reply.
Make sure it's complete and accurate.
