我整个早上都在尝试安装任何我的 16.04 VPS 上的 IRC 服务器。我遇到过很多其他问题，但现在每当我尝试安装任何 IRC 服务器时，我都会得到类似这样的信息：
Failed to validate path /var/run/inspircd.pid: Too many levels of symbolic links
fchownat() of /var/log/inspircd.log failed: Invalid argument
或者
Failed to validate path /var/run/ircd: Too many levels of symbolic links
Failed to validate path /var/run/ngircd: Too many levels of symbolic links
我真的不知道从哪里开始解决这个问题。我知道当您创建一个最终会循环回到自身的符号链接时可能会发生这种情况，但 /var/run/ 在尝试安装包之前不存在。除非正在安装的文件是指向现有符号链接的符号链接，而现有符号链接又指向此文件，否则我真的不知道该怎么做。
这是 ngircd 尝试失败后我尝试安装 inspircd 时 APT 的完整输出。
