From version 3.2 and onwards, when running management commands, the
registry is searched for the key 'Console'. In emulated environments (via
Wine) this fails as the key is nonexistent.

The code block where the error happens is:
{{{
def vt_codes_enabled_in_windows_registry():
"""
Check the Windows Registry to see if VT code handling has been
enabled
by default, see https://superuser.com/a/1300251/447564.
"""
try:
# winreg is only available on Windows.
import winreg
except ImportError:
return False
else:
reg_key = winreg.OpenKey(winreg.HKEY_CURRENT_USER, "Console")
# ERROR
try:
reg_key_value, _ = winreg.QueryValueEx(reg_key,
"VirtualTerminalLevel")
except FileNotFoundError:
return False
else:
return reg_key_value == 1
}}}
Moving the indicated line into the try/except block fixes the error.
