Run in project root directory:

Release new version without dependency upgrades

You only need to adjust git commit of lada in io.github.ladaapp.lada.yaml. Then create and merge a PR and given that the build pipeline ran through without issues wait a couple of hours before it becomes availalbe on Flathub.

Release new version with dependency upgrades

In Flatpak land it seems to be common practise to build our dependencies for source and not rely on pre-build binaries. This project is based on PyTorch/CUDA and there is no available SDK for flatpak for such projects so we have to rely on pre-build wheels from PyPi. req2flatpak helps with this scenario and this is what we use to convert the pip dependencies (available as requirements-gui.txt in lada upstream) to something flatpak can work with:

git clone https://github.com/ladaapp/lada.git # you maybe want to check-out a specific tag/commit here
cd lada
python -m venv .venv_build_flatpak
source .venv_build_flatpak/bin/activate
pip install req2flatpak
req2flatpak --requirements-file packaging/requirements-gui.txt --target-platforms 312-x86_64 > lada-pip-dependencies.json
deactivate

Now we have everything ready to build the flatpak. Commit lada-pip-dependencies.json, create a PR and let Flathub buildbot do its thing. For bigger changes you may want to build the flatpak yourself locally first to test and debug issues:

flatpak remote-add --if-not-exists --user flathub https://dl.flathub.org/repo/flathub.flatpakrepo
flatpak install --user -y flathub org.flatpak.Builder
mkdir flatpak
flatpak run org.flatpak.Builder --force-clean --sandbox --user --state-dir=flatpak/state --repo=flatpak/repo --install --install-deps-from=flathub --mirror-screenshots-url=https://dl.flathub.org/media/ flatpak/build  io.github.ladaapp.lada.yaml
