Quick install (Ubuntu Resolute)

This single script installs everything needed on one machine: the OST backend, the web interface, nginx, INDI, astrometry.net and the documentation you are reading right now.

1. Install a fresh Ubuntu 26.04

Install Ubuntu Server 26.04 LTS (“Resolute”) on the machine that will run OST — a Raspberry Pi, a mini-PC, or a virtual machine. Use the standard Ubuntu installer; no special option is needed.

Once Ubuntu is installed, open a terminal (directly on the machine, or over SSH from another computer).

2. Download the install script

Copy the command below, paste it into the terminal, and press Enter:

wget https://gitlab.ostserver.fr/ost/ostserver/-/raw/main/install-latest-complete.sh

Nothing happens on screen if it works — that is normal. A new file, install-latest-complete.sh, now exists in your current folder.

3. Run the script

chmod +x install-latest-complete.sh
./install-latest-complete.sh

The script then does everything by itself. A few things to expect:

• It will ask for your password a few times (sudo) — this is normal, it needs permission to install system packages.
• A blue screen may appear asking which astrometry.net index files to download in addition to the default ones. Use the arrow keys to move, Space to check/uncheck, Tab then Enter to confirm. If you are not sure, leave everything unchecked and press Enter — you can always add them later.
• It prints progress messages as it downloads and installs. This can take a few minutes depending on your Internet connection.

At the very end, it prints two addresses, for example:

Web UI: http://192.168.1.42/
Documentation: http://192.168.1.42/documentation/

Done

Open the first address (Web UI: ...) in a web browser, from any device on the same local network as the machine you just installed OST on. You should see the OST interface.
