Support policy
This PPA is provided as a convenience for Ubuntu users, with no guarantee of support. If you are an Ubuntu developer and would like to volunteer to maintain packages for this PPA, please contact us via https://github.com/flatpak/ppa-flatpak/issues.
Packages in this PPA are built for LTS branches of Ubuntu, currently 24.04 ‘noble’ and 22.04 ‘jammy’. The newest LTS branch is treated as the highest priority for updates.
Packages for Ubuntu 18.04 or older are generally no longer updated. Branches that have reached EOL for non-subscription-based updates are likely to stop receiving updates, or be removed from this PPA, when backports to those branches become too difficult.
Non-LTS branches such as groovy and hirsute are not currently supported by this PPA. If you are an Ubuntu developer and would like to volunteer to maintain packages for this PPA, please contact us via https://github.com/flatpak/ppa-flatpak/issues.
