Ubuntu 16.04安装ssh Temporary fail

早上安装Ubuntu ssh出现异常

Err:1 http://security.ubuntu.com/ubuntu xenial-security/main amd64 openssh-sftp-server amd64 1:7.2p2-4ubuntu2.7

Temporary failure resolving 'security.ubuntu.com'

Err:2 http://security.ubuntu.com/ubuntu xenial-security/main amd64 openssh-server amd64 1:7.2p2-4ubuntu2.7

E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/o/openssh/openssh-sftp-server_7.2p2-4ubuntu2.7_amd64.deb  Temporary failure resolving 'security.ubuntu.com'

E: Failed to fetch http://security.ubuntu.com/ubuntu/pool/main/o/openssh/openssh-server_7.2p2-4ubuntu2.7_amd64.deb  Temporary failure resolving 'security.ubuntu.com'

我的解决方法如下：

    echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/null

    sudo apt-get update

之后再安装SSH就没有问题

    sudo apt install openssh-server
