Hi,
Git-2.14.4 supports HTTPS.
The error ‘fatal: Unable to find remote helper for ‘https’’ occurs when GIT_EXEC_PATH is not set correctly.
The warning ‘warning: templates not found /var/rocket/git/share/git-core/templates’ occurs when GIT_TEMPLATE_DIR is not set correctly.
Probably, these variables unset before running git commands.
If you are using DBB, for example, please check if they are properly set in gitenv.sh
