El servidor Apache2 no puede iniciarse

Estoy intentando iniciar el servidor apache2 instalado en el escritorio Ubuntu 22.04 LTS. Sin embargo, el reinicio falló y, por lo que puedo ver en el registro de errores, está relacionado con mi configuración. Sin embargo, no puedo depurar más sobre el problema exacto. La configuración de mi servidor apache2 es la siguiente.

cat /etc/apache2/sites-enabled/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 webmaster@localhost
    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>

Al intentar iniciar el servidor

sudo service apache2 restart
Job for apache2.service failed because the control process exited with error code.
See "systemctl status apache2.service" and "journalctl -xeu apache2.service" for details.

Profundizando más en el estado de systemctl apache2.service, parece que tengo un problema en la línea 18 de mi archivo de configuración de apache2. Revisé esa línea y no puedo ver exactamente cuál es el problema.

systemctl status apache2.service

También verifiqué el archivo error.log y obtuve la siguiente impresión. Todavía no estoy seguro de cuál es el problema exacto.

Si usa el comando cat -teven lugar de catenumerar el contenido del archivo /etc/apache2/sites-enabled/000-default.conf, verá que las líneas 18 y 19 contienen algunos caracteres de control extraños, algo como estos:

[...]
    <Directory /home/hd2900/Documents/Python/hd2900TakeawayPrint>$
    M-bM-^@M-^F M-bM-^@M-^F M-bM-^@M-^F M-bM-^@M-^F M-bM-^@M-^F WSGIProcessGroup flaskapp$
    M-bM-^@M-^F M-bM-^@M-^F M-bM-^@M-^F M-bM-^@M-^F M-bM-^@M-^F Require all granted$
    </Directory>$
[...]

Probablemente hayas copiado y pegado estas directivas desde una página web o PDF.

Debe eliminar las líneas 18 y 19 de este archivo y volver a ingresar las directivas de configuración manualmente en el mismo lugar:

WSGIProcessGroup flaskapp
Require all granted
