我正在尝试安装 VNC 服务器putty，但它没有安装。
我已经运行以下命令来安装
sudo apt-get install gnome-coresudo apt-get install vnc4servervncserver
我收到以下错误，是什么原因造成的？
msfl@chanakyauat:~$ sudo apt-get install vnc4server

E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
msfl@chanakyauat:~$ vncserver
No command 'vncserver' found, did you mean:
Command 'vnc4server' from package 'vnc4server' (universe)
vncserver: command not found
msfl@chanakyauat:~$
msfl@chanakyauat:~$ vnc4server
The program 'vnc4server' is currently not installed. You can install it by typing:
sudo apt-get install vnc4server
答案1
您的系统报告：
Something wicked happened resolving 'us.archive.ubuntu.com:http' (-5 - No address associated with hostname)
接下来是大量Failed to fetch显示该主机名和security.ubuntu.com.
主机名us.archive.ubuntu.com对我来说解析为 IPv4 和 IPv6 地址（技术上A和AAAADNS RR）。
由于 URL 本身看起来很正常，因此我倾向于认为附加的内容是在发生故障时:http如何显示主机名的人为因素，而不是它尝试连接的主机名的实际部分。apt-get
因此，我倾向于相信你的问题在于VNC 以外的其他地方。具体来说，我相信您的问题一般在于 DNS 解析。
修复您的名称解析设置，并且apt-get也应该开始工作。这应该允许您安装 VNC 以及系统显然急需的安全更新。
答案2
但在系统日志输出的最后一行中，报告程序找不到“vncserver”并提供使用 vnc4server。
你试一试：
msfl@chanakyauat:~$ vnc4server
