我在云中的 Ubuntu 20.04 实例上安装了 mailman3。首先，它无法启动，现在我彻底重新安装了，现在它正在运行。我可以创建一个邮件列表，其余运行器正在运行。
我现在想知道我需要做什么才能访问 Postorius Web UI。我将文件复制apache.conf到我的 apache2sites-enabled目录，但我认为它使用的 URL 上仍然没有显示任何内容。文档说 URL 是ipnr/postorius/lists。对吗？如果我得到 404，我错过了什么？
这是 sites-enabled 中的 apache2 conf 文件：
Alias /mailman3/favicon.ico /var/lib/mailman3/web/static/postorius/img/favicon.ico
Alias /mailman3/static /var/lib/mailman3/web/static
<Directory "/var/lib/mailman3/web/static">
Require all granted
</Directory>
<IfModule mod_proxy_uwsgi.c>
ProxyPass /mailman3/favicon.ico !
ProxyPass /mailman3/static !
ProxyPass /mailman3 unix:/run/mailman3-web/uwsgi.sock|uwsgi://localhost/
</IfModule>
这是输出自systemctl status mailman3：
