使用wget时遭遇“unable to resolve host address”错误求助

我刚接触Linux系统，最近买了一本带实操实验的书，打算通过VirtualBox来学习Kali Linux。不过当我尝试用wget命令下载文件时，遇到了下面的错误提示：

Resolving hackerhousebook.com (hackerhousebook.com)... failed: Temporary failure in name resolution
wget: unable to resolve host address 'hackerhousebook.com'

我执行的原始命令是：

$ wget --user username --password password https://hackerhousebook.com/files/wordlists.tgz
