执行更新数据(sudo apt-get update)提示:
Err http://mirrors.aliyun.com trusty Release.gpg Could not resolve ‘mirrors.aliyun.com‘ Err http://mirrors.aliyun.com trusty-updates Release.gpg Could not resolve ‘mirrors.aliyun.com‘ Err http://mirrors.aliyun.com trusty-backports Release.gpg Could not resolve ‘mirrors.aliyun.com‘ Err http://mirrors.aliyun.com trusty-security Release.gpg Could not resolve ‘mirrors.aliyun.com‘ Reading package lists... Done W: Failed to fetch http://mirrors.aliyun.com/ubuntu/dists/trusty/InRelease
此时只要编辑网络DNS配置文件即可:
sudo gedit /etc/resolv.conf
在弹出的文本里最下面加入:
cat /etc/resolv.conf
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.8.8 nameserver 8.8.4.4
重启网络：
sudo /etc/init.d/networking restart
再次执行3步:
sudo apt-get update
执行完成,然后:
sudo apt-get upgrade
大功告成!
