Error installing: No module named file_manager

I’ve just found this thread and switching to the staging branch:

git clone https://github.com/frappe/bench.git .bench
cd .bench
git checkout -b staging
cd
pip install --user -e .bench
.local/bin/bench init frappe-bench --frappe-branch staging
cd frappe-bench
../.local/bin/bench new-site --mariadb-root-username root --mariadb-root-password XXX  --db-name erpnext --admin-password YYY $( hostname -f)

And this works… is the staging branch the best one to use for production then?
