Python Error while installing

Hi,

after being taught a lesson the last time not to mess with the configuration of MiaB i got back to a default installation.

After starting with “curl -s https://mailinabox.email/setup.sh | sudo bash” i get to enter the host-name, the inital mail address and after entering the password i get the following message on the shell:

500 Internal Server Error

Internal Server Error

The server encountered an internal error and was unable to complete your request. Either the server is overloaded or there is an error in the application.

Your Mail-in-a-Box is running.

Please log in to the control panel for further instructions at:
