This project intends to simplify the sysupgrade process of devices running OpenWrt or distributions based on the former like LibreMesh. The provided tools here offer an easy way to reflash the router with a new version or package upgrades, without the need of opkg installed.

Additionally it offers an API (covered below) to request custom images with any selection of packages pre-installed, allowing to create firmware images without the need of setting up a build environment, even from mobile devices.

Simple web interface using vanilla JavaScript currently developed by @mwarning. It offers a device search based on model names and show links either to official images or requests images via the asu API. Please join in the development at the GitLab repository

The package luci-app-attendedsysupgrade offers a simple view under System > Attended Sysupgrade to automatically request a new firmware, wait until it's built and flash it.

It's possible to upgrade routers via a command line interface called auc.

The server listens to image requests and automatically generate them if the request was valid. This is done by automatically setting up OpenWrt ImageBuilders and cache images in a Redis database. This allows to quickly respond to requests without rebuilding existing images again.

• chef.libremesh.org

Redis is required to store image requests:

sudo apt install redis-server tar

Install asu:

pip install asu

Start the server via the following commands:

export FLASK_APP=asu.asu  # set Flask app to asu
flask janitor update      # download upstream profiles/packages
flask run                 # run development server

Start the worker via the following comand:

rq worker

It is recommended to run ASU via gunicorn proxied by nginx. Find a possible nginx configuration in the misc/ folder. Also the setup should not HTTPS to allow clients without SSL/certificates to check for upgrades.

To change the default setting place a file called config.py in the root of the instance folder. Find an example in the misc/ folder.

pip install gunicorn
gunicorn "asu:create_app()"

After cloning this repository create a Python virtual environment and install the dependencies:

python3 -m venv .
source bin/activate
pip install -r requirements.txt
export FLASK_APP=asu.asu  # set Flask app to asu
export FLASK_DEBUG=1      # run Flask in debug mode (autoreload)
flask run

The server does no longer offer complex upgrade check but only static JSON including available branches and versions. The client must evaluate itself if the responded JSON contains a newer version.

The server responds with the latest versions of the same or newer branches. A client should always suggest the latest release of the same branch, however advanced users may also want to upgrade to a different branch. Branches are for instance openwrt-18.06 and openwrt-19.07, where it is for a running 18.06.2 device safer to upgrade to 18.06.7 than to 19.07.3.

Snapshots are not shown in this list.

Returns the configured branches. The content is based on the BRANCHES variable in the configuration, an example is available in ./misc/config.py.

Each valid request returns a request_hash which can be used for future polling via /api/build/<request_hash>.

A 200 response means the image was sucessfully created. The response is JSON encoded containing build information.
