Method 3: Install script, offline

Use this when the server can’t download from GitHub (no internet, or GitHub is filtered).

Step 1: Download the package on another computer, from Releases:

  • flock-server-linux-x64.tar.gz (most servers) or flock-server-linux-arm64.tar.gz (ARM servers; check with uname -m)
  • the matching .sha256 file (optional, to verify the download)

Step 2: Copy them to the server, for example:

Terminal window
scp flock-server-linux-x64.tar.gz* user@your-server:~

Step 3: Unpack and verify

Terminal window
sha256sum -c flock-server-linux-x64.tar.gz.sha256     # should print "OK"
tar -xzf flock-server-linux-x64.tar.gz

Step 4: Make sure PostgreSQL is available. The package contains everything except the database. Either:

  • let the installer install PostgreSQL. This needs the OS package sources (apt/dnf), which often work even when GitHub doesn’t, or
  • install it yourself from local media or a mirror (sudo apt install postgresql / sudo dnf install postgresql-server), or
  • use an existing database with --db-url postgres://user:pass@host:5432/flock in the next step.

Step 5: Install

Terminal window
sudo ./flock-server/install.sh --domain chat.example.com

It accepts the same options as method 2. --domain needs the server to reach Let’s Encrypt; without it, Flock answers on http://<server-ip>:4000.

Updating: download the new package the same way and run its install.sh (or sudo flockctl update --package /path/to/package.tar.gz). Configuration and database are kept. flockctl works as in method 2.

For a fully manual installation (no script), see deploy/INSTALL.md.
