Syncthing updater

Syncthing v1.x has syncthing serve -u, which upgrades the binary without loading syncthing itself.

Syncthing v2.x auto upgrade requires the syncthing service to be able to write the binary. If you have syncthing in /usr/bin/ you either have to boot the syncthing server as root or manually replace the binary.

This script brings back the old auto upgrade to syncthing v2.x.

Installation

For windows users

This script right now does not (and probably will never) support the .zip files used to distribute windows binaries of syncthing.

Just use GermanCoding's synctrayzor.

Getting the code

Download the ZIP with the latest changes and unzip it

or

Clone the repo with git:

git clone https://github.com/Omicron166/syncthing-updater.git

Installing dependencies

This script requires requests and packaging to work. Additionally, you can install tqdm to have a download progress bar (or avoid it using --no-tqdm)

You can either install the dependencies on a virtual enviroment or install them as python3-requests python3-packaging python3-tqdm on debian based distros.

Configuration

The available options are very straightforward.

• bin_path is the path to the syncthing binary.
• upgrade_url is the url of the syncthing upgrade server, don't change it unless you know what you're doing.
• architecture is the version of syncthing to download. Run list-architectures.py and select yours.
• download_prereleases indicates if you want to download syncthing prereleases (true) or just the stable releases (false)
• download_path is the path where temporal files will be stored.
• download_cleaning indicates if you want to remove (true) or keep (false) the temporal files after upgrading syncthing.

You can either copy and fill config_sample.json or run the interactive config generator gen-config.py.

Usage

$ python3 main.py -h
usage: main.py [-h] [-c CONFIG] [--force] [--dry-run] [--no-tqdm]

A script for syncthing v2.x that mimics the syncthing v1.x auto upgrade from cli

options:
  -h, --help            show this help message and exit
  -c CONFIG, --config CONFIG
                        Path to the json config file (config.json by default)
  --force               Replace the binary without checking the version
  --dry-run             Do not replace the binary
  --no-tqdm             Disable the download progress bar, tqdm is not required if this option is used

Install syncthing or update from v1.x

By using the --force option, you can install syncthing, reinstall it if you forgot to change the settings and got the amd64 version on a raspberry pi or update syncthing from v1.x to v2.x. If you try to update syncthing v1.x without this option, the script will crash.

Tested systems

• Raspberry Pi OS 64 bit (raspberry pi 3b)
• Linux Mint 21.3 (x86_64 PC)
