给ubuntu选择最快的更新源
1、打开设置》》软件和更新,如下图
2、下载自:下拉菜单,选择其他站点
3、你可以选择最佳服务器,也可以指定你满意的服务器。选择之后要求输入密码
4、选择关闭,之后会重新自动执行更新命令(sudo apt-get update),更新完成
安装Ubuntu18.04后,使用国外源太慢了,修改为国内源会快很多。
修改阿里源为Ubuntu 18.04默认的源
备份/etc/apt/sources.list
#备份
cp /etc/apt/sources.list /etc/apt/sources.list.bak
在/etc/apt/sources.list文件前面添加如下条目
#添加阿里源
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
最后执行如下命令更新源
##更新
sudo apt-get update
sudo apt-get upgrade
另外其他几个国内源如下:
