Ubuntu 25.04 has been unsupported for over a month. How will sprites get security and feature upgrades?

In my sprites, more /etc/lsb-release says

…. DISTRIB_DESCRIPTION=“Ubuntu 25.04”

But Ubuntu 25.04 has been unsupported for over a month, since Jan 15 2026.

I created another sprite just now, and it is unsupported from the get-go. Not a good look…

The question in a few other queries here (now closed) is, how will sprites get security and feature upgrades?

And when you roll out a new base VM, how can we most efficiently move / port / test our stuff for a new sprite? Can we re-use the old name somehow?

Sprites are awesome, but this is a pretty big issue right now.

(I started this new topic since my last one from Feb 1 went unanswered for 7 days and was auto-closed. Let’s keep this one alive.)

Thanks!

I did a sprite upgrade and got to v0.0.1-rc39, but that only affected files in /.sprite.

It seems to use normal Ubuntu repos:

$ grep http /etc/apt/sources.list.d/ubuntu.sources
...
URIs: http://archive.ubuntu.com/ubuntu/
URIs: http://security.ubuntu.com/ubuntu/

In order to run do-release-upgrade I installed it:

$ sudo apt install ubuntu-release-upgrader-core

then ran it.

Then it asked me to do some updates, noting 277 packages out-of-date.

$ sudo apt update

$ sudo apt upgrade

…

Not upgrading:
dirmngr gnupg gnupg-utils gpg gpg-agent gpgconf gpgsm gpgv

Summary:
Upgrading: 277, Installing: 21, Removing: 0, Not Upgrading: 8
Download size: 312 MB
Space needed: 267 MB / 105 GB available

Now I see 25.10, which is still getting security updates.

sprite@sprite:~$ more /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=25.10
DISTRIB_CODENAME=questing
DISTRIB_DESCRIPTION=“Ubuntu 25.10”

Of course, it also means I’m paying for more disk space.

So I’m still wondering what the official procedures will be.
