I have a simple question, has Ubuntu 23.10 been released? Why I ask is when I query the release information, it comes back negative:
david@david-XPS-15-9530:~$ sudo do-release-upgrade

Checking for a new Ubuntu release
No new release found.
Also in the Software & Updates app, I have Any new version marked for any new releases, and no notification has been given.
Depending on what version of Ubuntu you are trying to upgrade FROM you may have no upgrade target when running do-release-upgrade. For example, my installation of Ubuntu 22.04 LTS cannot upgrade to 23.10 because 23.10 is not a valid target for my Ubuntu installation.
Running sudo do-release-upgrade Ubuntu 22.04 the default settings output
There is no development version of an LTS available. To upgrade to the latest non-LTS development release set Prompt=normal in /etc/update-manager/release-upgrades.
If you open /etc/update-manager/release-upgrades it is probable that you are set to Prompt=lts which will not allow you to go to 23.10 because 23.10 is not a LTS release.
You can however try setting Prompt=normal and it will look for the next release that is a valid release and allow you to update to that target.
