I was given a running erpnext/frappe instance, running version 15.18.1 for erpnext and frappe 15.19.0. I planned on installing the hrms app and updating the existing applications, but when I bench update I get the error
‘subprocess.CalledProcessError: Command ‘git symbolic-ref -q --short HEAD’ returned non-zero exit status 128.’
any help with resolving this would be greatly appreciated
