我是 Ubuntu 的新用户，我正在尝试在其中安装 gromacs 5.1.4，但在安装的最后几步，我收到一条错误消息，提示网络无法访问。我还在这里添加了代码，以防万一。

答案1
问题似乎是从服务器到 ftp.gromacs.org 的网络连接。您能 ping 到这个位置吗？
ping ftp.gromacs.org
如果是，您能看看 wget 是否正在获取该文件吗？
wget ftp://ftp.gromacs.org/regressiontests/regressiontests-5.1.4.tar.gz
您也可以尝试在 /etc/resolv.conf 文件顶部添加一个条目，然后重试。
nameserver 8.8.8.8
如果这些都不起作用，我猜是防火墙阻止了连接。
答案2
我在通过 wget 下载时也遇到了问题。因此我使用浏览器下载了软件包。
它只是暂时解决了我的问题。
