Ubuntu Core Desktop 25.04

Pre-Release Discussion
1

I mis the following snaps in the Ubuntu Core Desktop 25.04:

  • VBox Guest Additions, many people will try this flavor in Virtualbox and it would be nice, if they could use all functions of Virtualbox. For me it is essential because I run all my Apps in VBox VMs. I use a Ubuntu 16.04 ESM VM (VBox encrypted) exclusively for banking, and in 2026, after 10 years with 16.04, I like to replace it by the Ubuntu Core Desktop 26.04 LTS :slight_smile:
  • Conky, I watch the detailed state of Host and VMs using conky, so a snap for conky would be nice :slight_smile:
  • Ubuntu-bug, or another snap to report bugs we detect. Today after a snapd update all icons disappeared in the dock and gnome menu, so I had to revert the snapd update.

No, I tried the 24.04 version, but when the release was cancelled, I deleted it. I did not have the impression, that much happened afterwards. And now I found it back in an ISO file (from begin October) in the Ubuntu Development Editions under Experimental/Ubuntu Desktop Core.

It does not sound like there is a lot of confidence in Canonical for this development, because there are no publications in e.g. OMG Ubuntu or elsewhere. It looks like they try to keep it secret by hiding the ISO.

I installed the ISO on Sunday, did run the updates on Sunday, Monday and Tuesday. Tuesday the update of snapd failed. There are some updates since its creation, but not very many and mainly the standard snaps.

I’m close to 80, but I understand the potential of this development, because I worked in IT from 17-3-69 till 1-1-11. I could help with testing and maybe I could create a snap or two.

I have had no success with either of the two Ubuntu Core Desktop ISO images. My success came with writing the image.xz file to a 16 GB USB stick. That works well. It is a different way of installing a Ubuntu desktop image.

On https://cdimage.ubuntu.com/experimental/ubuntu-core-desltop/24/stable/ I still only see two ISO images. The latest from 07/10/2024. Where did you get a Ubuntu Core Desktop 25.04 ISO image from?

From my studies of Ubuntu Core Desktop it is built on Ubuntu Core 22. It has still to transition to Ubuntu Core 24. With Ubuntu Core Canonical has stayed with LTS releases.

Regards

Yes, that is the ISO image I found, and I assumed that it would become 25.04, because almost all other flavors in that main directory are the development editions of 25.04.
In the past during the development of the 24.04 version of the core-desktop I also used last image.xz files and I think, I converted it to a vdi file using a VirtualBox command.

I checked the VM and it is now Core 24 with Linux 6.8.0-48.

Since the installation on Sunday ~16 snaps have been updated by the App-Center (application snaps and Linux snaps), one on Monday and snapd, the one I had to revert, on Thursday. I will continue to keep an eye on it.

I received two new snaps during the upgrade, one for the desktop integration and the other for the upgrade of the kernel to 6.8.0-50. The installs were done, but both did give an error message at the end about “an unknown error”, but I verified the result and he Core-Desktop runs the newer kernel and also the newer desktop-integration has been installed.

Hi there, Graymech.
When I started my work on Slumberer Sentinels, I was planning on using Ubuntu because it actually has commentary on the Modern Slavery Act, and other social commentary on values I appreciate. When I found out Fedora and RedHat were doing CoreOS (? ^^; ) with bootc and atomic images, I was wondering if Ubuntu was failing to miss this valuable act. What actually happened was I finally had the language to know how to search for Ubuntu’s own work on this necessary and valuable version of operating systems, and I found out about Ubuntu Core Desktop. But only through news articles. I couldn’t find a download for the experimental for me to test out. Until now. Thanks to you and this thread about the latest upcoming Core Desktop version, 25.04.

Thank you all for keeping this discussion going, Ubuntu, AnboxCloud, and containerized operating systems for more reliable desktops (versus personal use ones) is the future I’m trying to bring to the present and everybody. I don’t know if I’ll be able to get Foreman working like this, but that’s a problem for later.

Thank you, @lammert-nijhof and @graymech . (You too, anmac1789 ).

Ubuntu needs to keep working on this because it one of the most valuable instances of Ubuntu that is about to be commonplace. Without it, only RedHat, Fedora, SUSE, Arch, and all sorts of other instances will have a commonplace, secure, and reliable operating system for users who won’t have the time to dig into Linux internals. It’ll also allow BTRFS and other security mechanisms like TPM to protect these devices.

Canonical, please. If anybody makes you doubt the value of Atomic images like Core Desktop, send them a picture of me staring angrily into the camera at their attempted sabotage of Canonical. We’re steps away from big corporations saying it’s easy to deploy Ubuntu as a standard across OpenStack, since even users like me are doing it in my own with EVE-OS.

I hope. I’m taking this image and you’re going to have to pry it from my cold, dead hands.

PS: There’s an "L " in the URL where it should be a K.

PPS: Wait, there’s no ARM version for my Raspberry Pi? Rip, lol. I guess I can only do this for my desktops, let me see if I can find any build details and build one my own. :pleading_face:
