Windows Subsystem for Linux (WSL) has some permission issues when trying to modifying files in the Windows file system (/mnt):

Traceback (most recent call last):
  File "agscore.py", line 425, in <module>
    if rename() != 0:
  File "agscore.py", line 49, in rename
    os.rename(entry.name, ' '.join(n))
PermissionError: [Errno 13] Permission denied: 'xxx_assignsubmission_file_' -> 'xxx'

This bug does not appear in cmd.
