so i cant go further
i also tried to chmod +x on manage.py also linked the python3 sudo ln -s /usr/bin/python3 /usr/bin/python so it detects the python env
even in sudo it wont run

in file
webvirtmgr/webvirtmgr/utils/secret_key.py in line 60: Change

if oct(os.stat(key_file).st_mode & 0o777) != '0600':

to

if oct(os.stat(key_file).st_mode & 0o777) != '0o600':

and use:

$ sudo chmod 0600 webvirtmgr/webvirtmgr/local/.secret_key_store
