Package for Ubuntu 24.04 and Debian 12 or newer, amd64 and arm64, with systemd. It sets up Docker if needed, runs Submify in Docker with a PostgreSQL database and generated secrets, and starts it. Read the script first, or download the .deb and run sudo apt install ./file.deb.

One command (downloads the latest release, checks its SHA-256, installs it)

The Ubuntu / Debian package

  • Installs a systemd service that runs the version-pinned Submify containers with Docker Compose. It is labelled “runs in Docker” because it is not a native binary.
  • Installs Docker first if it is missing, and checks the download’s SHA-256 before installing.
  • Generates database passwords and secrets on first install into /etc/submify/submify.env (mode 0600). They survive upgrades, removal and purge.
  • Opens on http://localhost:2512.

Update by running the installer again, or sudo apt install ./submify_<version>_amd64.deb. Remove with sudo apt remove submify; settings and the Docker volumes (submify_pg_data and submify_uploads) are kept. Back up before upgrading.
