When creating a repository with seamm-cookiecutter, one should use one of the newer versions of git (e.g., > 2.17) that allows dealing with the main branch name change (master-> main) when initializing the repository.
This compatibility issue with git 2.17.1, which is standard on e.g. Ubuntu 18.04 LTS, has been fixed as of version 2022.8.24.1 of the seamm-cookiecutter. You can easily check the version of seamm-cookiecutter with conda list seamm-cookiecutter
and update it with either seamm-installer update
or pip install -U seamm-cookiecutter
