在此我确实尝试解决红色错误：
-
- PHP 配置选项 output_buffering 必须被禁用路径：/etc/php/8.1/apache2/php.ini
; output_buffering
; Default Value: Off
; Development Value: 4096
; Production Value: 4096
正如您所见，所有内容都已改变，但仍显示错误。
-
- 您的数据目录和文件可能可以通过互联网访问。.htaccess 文件不起作用。强烈建议您配置 Web 服务器，使数据目录不再可访问，或将数据目录移出 Web 服务器文档根目录。
路径：/etc/apache2/sites-available 以及 nextcloud.conf
我改变的代码是
GNU nano 6.2 nextcloud.conf
<VirtualHost *:80>
ServerAdmin **mymail**
DocumentRoot /var/www/nextcloud/
ServerName **my ip-address**
Alias /nextcloud "/var/www/nextcloud/"
Redirect 301 /.well-known/webfinger /nextcloud/index.php/.well-known/webfinger
<Directory /var/www/nextcloud/>
# Options +FollowSymlinks
# AllowOverride All
Require all denied
# Require all granted
# <IfModule mod_dav.c>
# Dav off
# </IfModule>
# SetEnv HOME /var/www/nextcloud
# SetEnv HTTP_HOME /var/www/nextcloud
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
忽略 http 错误、smtp 和 default_phone_region 错误和警告
现在来看看剩下的 /.well-known/ 警告。如何解决它们我试过解决它，代码是
路径：/etc/apache2/sites-available
在这里，我有 2 个 conf 文件，但不知道要修改哪个，因此我一个接一个地进行了修改，但警告并未出现
000-default.conf default-ssl.conf nextcloud.conf
对于 nextcloud.conf 我尝试解决一个错误 /.well-known/webfinger
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot /var/www/nextcloud/
ServerName 192.168.1.105

对于 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

# For most configuration files from conf-available/, which are

# 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>
# vim: syntax=apache ts=4 sw=4 sts=4 sr noet
在 ServerAdmin 中我必须添加我的电子邮件吗？
所以这些是我想要解决的主要问题，因为这是我第一次使用 nextcloud。
谢谢。
