Technically the release is just new media; as outlined in the first [news] post I provided
As usual, this point release includes many updates and updated installation media has been provided so that fewer updates will need to be downloaded after installation. These include security updates and corrections for other high-severity bugs, with a focus on maintaining stability and compatibility with Ubuntu 24.04 LTS.
This applies to flavors like Lubuntu too, though this release has significance for users of the prior LTS, as the taps allowing upgrade from prior LTS will soon open too.
If interested in some of the bugs fixed, please refer to
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.
What I posted was part of a mailing list thread, and I quoted only the detail that I felt related to anyone currently using Lubuntu 22.04 LTS, and was thinking about trying to release-upgrade to Lubuntu 24.04 LTS, and thus may run into the blockage…
I noticed it in the morning (doing Ubuntu News stuff; we won’t act until next bit occurs) and ignored it before many hours later decided to post here (& UM) as it may trip up any users who were told upgrade was open. Whilst I’ve not seen the bug ID mentioned that was referred to, I did find a bug in jammy proposed for apt that may see a fix somewhat soon, but we’ll have to wait & see (could also be that’s not the bug Utkarsh was talking about).
I’m hoping for more detail to come…
Currently we just know jammy/22.04 release-upgrades to noble/24.04 are NOT open.
Upgrades from 22.04 to 24.04(.1) are enabled again
Julian Andres Klode tells us …
Last Wednesday, we temporarily suspended upgrades to Ubuntu 24.04.1 LTS due to unforeseen issues with dependencies of installed kernel headers after release upgrades. These issues were tracked in bug 2078720 and have now been resolved, and upgrades to 24.04.1 LTS have been enabled again. Read on to see if you’re affected and how you can apply a fix.
