Ubuntu 16.04:Temporary failure resolving 'security.ubuntu.com'

Ubuntu 16.04:Temporary failure resolving 'security.ubuntu.com'

今天早上对软件源进行更新的时候，发现出现了如下的错误：

W: Failed to fetch Temporary failure resolving 'security.ubuntu.com'W: Some index files failed to download. They have been ignored, or old ones used instead.

我的解决方法为：

echo "nameserver 8.8.8.8" | sudo tee /etc/resolv.conf > /dev/nullsudo apt-get update

然后就一切正常了，我的输出为：
