Apache2 サーバーを起動できません

Ubuntu 22.04 LTS デスクトップにインストールされている apache2 サーバーを起動しようとしています。しかし、再起動に失敗しました。エラー ログを見ると、これは私の構成に関連しているようです。ただし、正確な問題についてはこれ以上デバッグできません。私の apache2 サーバーの構成は次のとおりです。

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

    # modules, e.g.
    #LogLevel info ssl:warn

    # 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>

サーバーを起動しようとすると

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.

systemctl status apache2.service をさらに詳しく調べたところ、apache2 構成ファイルの 18 行目に問題があるようです。その行を確認しましたが、問題が何なのか正確にはわかりません。

error.log も確認し、以下の出力を取得しました。正確な問題が何であるかはまだわかりません。

cat -tevの代わりにコマンドを使用してcatファイル の内容を一覧表示すると/etc/apache2/sites-enabled/000-default.conf、行 18 と 19 に次のような奇妙な制御文字が含まれていることがわかります。

[...]
    <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$

おそらく、これらのディレクティブは Web ページまたは PDF ページからコピーして貼り付けたものです。

このファイルの 18 行目と 19 行目を削除し、同じ場所に構成ディレクティブを手動で再入力する必要があります。

WSGIProcessGroup flaskapp
