index
The tuna-os/ubuntu repository was archived on 2026-08-12.
This page is kept for historical reference only; no new builds are
published from this repo. Ubuntu 26.04 images are now built and published
from the main tunaOS pipeline as the
Grouper variant — see tunaos.org/download
for current builds.
Successor images
The standalone ghcr.io/tuna-os/ubuntu:26.04 image and its ISO workflow are
retired. Do not use the archived repository's pull, switch, or download
instructions for a new installation.
Choose the maintained in-tree successor that matches the Ubuntu release you need:
| Ubuntu base | TunaOS variant | Start here |
|---|---|---|
| Ubuntu 26.04 | Grouper | Grouper overview and technical guide |
| Ubuntu 24.04 LTS | Gurnard | Gurnard overview |
Use the download page for published ISOs. It is the canonical source for current artifacts; a missing variant there should not be inferred to have a supported "latest" build.
Historical source
The archived tuna-os/ubuntu repository is retained for source history only. Its last commit was published without a GitHub Release or a supported migration contract. Existing users should choose an in-tree successor above rather than switching to an archived image tag.
