Failed to fetch http://mirrors.tuna.tsinghua.edu.cn/ubuntu/pool/main/g/gcc-5/g++-5_5.4.0-6ubuntu1~16

今天在ubutun中在安装redis过程中，安装gcc时遇到了Failed to fetch http://mirrors.tuna.tsinghua.edu.cn/ubuntu/pool/main/g/gcc-5/g++-5_5.4.0-6ubuntu1~16。

后在/etc/resolvconf/resolv.conf.d/base中添加nameserver  202.96.134.133     nameserver  202.96.128.68(电信)

运行sudo apt-get install gcc

成功安装
