Make sure you're either building from a fully intact git repository or PyPI tarballs. Most other sources (such as GitHub's tarballs, a git checkout without the .git folder) don't contain the necessary metadata and will not work.

For example, if you're using pip, instead of https://github.com/user/proj/archive/master.zip use git+https://github.com/user/proj.git#egg=proj

joe_yee923: how did you download the code? Did you git clone?

In reply to @reivilibre.element:librepush.net
Try using git clone rather than using the zip download

It works for me; can you double check you have a .git directory in the repository?

e.g. ls .git

Ok now i get this below error

docker run -it matrixdotorg/sygnal

In reply to @reivilibre.element:librepush.net
you will need to write a configuration file and mount it into the container

Ok now i got it running but it seems we need to define the appID's in the sygnal.yaml file to get this working properly.

sounds like your configuration isn't properly formatted
