Just another informational notice...
Upgrades from 22.04 LTS to 24.04 LTS are no longer open... No official notice yet exists (I'll amend this when I have one), so for now I'll use
https://lists.ubuntu.com/archives/ubuntu-release/2024-September/006225.html
the upgrade was disabled due to a critical bug in ubuntu-release-upgrader in the way it's using the apt solver. This is being worked on and as soon as this is fixed, we'll re-enable the upgrades.
We're also working on an announcement post/mail so that people are aware.
As 24.04 or noble has been removed from https://changelogs.ubuntu.com/meta-release , if you don't want to wait, you'll need to use the -d option for force upgrade; but waiting until it's open would be a safer alternative.
