打开终端，cd /etc/apt下，cat sources.list文件，看看。

如果还不行，进行临时文件清理。sudo rm -rf /var/lib/apt/lists/*
然后再执行 sudo apt-get clean && sudo apt-get update && sudo apt-get upgrade

根据楼主提供的日志信息，是使用的陕西省西安市 长城宽带网络吗？https://bbs.deepin.org/post/37765这是坛内之前遇到的问题。一般原因是出在了网络服务运营商，你改DNS（114.114.114.114）再运行。

好的，谢谢你的帮助

你好，修改了DNS服务器后，再次更新错误:3 http://180.89.255.51/files/41160 ... s.deepin.com/deepin lion/main amd64 Packages
