The mailing list for listmasters using Sympa

[Pierre Abbat <address@concealed>]

I'm trying to set up a new mailing list server and got an internal server 
error when I set up the web service for Sympa. The error log of Apache looks 
like this:

Here is 000-default.conf:

<VirtualHost *:80>
        # The ServerName directive sets the request scheme, hostname and port 
that
        # the server uses to identify itself. This is used when creating
        # redirection URLs. In the context of virtual hosts, the ServerName
        # specifies what hostname must appear in the request's Host: header to
        # match this virtual host. For the default virtual host (this file) 
this
        # value is not decisive as it is used as a last resort host 
regardless.
        # However, you must set it for any further virtual host explicitly.
        #ServerName www.example.com

        ServerAdmin address@concealed
        DocumentRoot /var/www/html

        # For most configuration files from conf-available/, which are
        # enabled or disabled at a global level, it is possible to
        # include a line for only one particular virtual host. For example the
        # following line enables the CGI configuration for this host only
        # after it has been globally disabled with "a2disconf".
        #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

wwsympa.fcgi looks like this:

#!/bin/bash
# Path to your real wwsympa.fcgi
exec /usr/lib/cgi-bin/sympa/wwsympa.fcgi

wajig> versions apache2 sympa
apache2:amd64/xenial-security 2.4.18-2ubuntu3.5 uptodate
sympa:amd64/xenial 6.1.24~dfsg-1 uptodate

How should I fix it?

(Je comprends le français mais je manque de pratique en parlant.)
