我正在尝试使用设置服务器LXD 容器和Ubuntu/Debian 映像，但经常遇到安装问题资质。在此示例中，我想设置一个舒适的服务器。
Setting up <package> (version) ...例如，Aptitude 完全符合该标准
Setting up rsync (3.1.1-3) ...
Failed to execute operation: Connection timed out
dpkg --configure --all当我中止它并重新启动安装时，它告诉我由于安装中止而运行。这很有道理。但是该命令再次导致相同的问题。取消进程 dpkg 然后打印
Errors were encountered while processing:
rsync
supervisor
nginx-full
(and many more ...)
然后我想尝试单独安装/配置软件包，这样我就可以解决问题。我输入apt-get --configure supervisor了
dpkg --configure supervisor
Setting up supervisor (3.0r1-1) ...
Failed to get D-Bus connection: No such file or directory
Failed to get D-Bus connection: No such file or directory
Failed to get D-Bus connection: No such file or directory
invoke-rc.d: initscript supervisor, action "start" failed.
dpkg: error processing package supervisor (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
supervisor
从现在起我该如何排除故障？我该如何找出配置失败的原因？据我所知，有些初始化失败了。我真的被困在这里了。
