pgAdmin Flatpak

This project uses uv. Make sure to have it installed.

uv venv
source .venv/bin/activate
uv pip install requirements-parser packaging

You can regenerate pip dependencies with the script regen-pip.sh, but you will need to have krb5-config and libpq-devel installed on your system due to a wheel needing it.

./regen-pip.sh

Build flatpak:

flatpak run org.flatpak.Builder build-dir --user --ccache --force-clean --install org.pgadmin.pgadmin4.yml

Then you can run it via the command line:

flatpak run org.pgadmin.pgadmin4

or just search for the installed app on your system

Important

If you get No matching distribution found for backports.zstd; python_version < "3.14" from python3-Flask-Compress while building the Flatpak, add the dependency manually. Grab the download URL and SHA256 from the backports.zstd PyPI "Download files" section and include them in your sources. This could happen with python3-google-api-python-client and its dependency cachetools.
