【Ubuntu】Ubuntu 18.04 LTS 更换国内源——解决终端下载速度慢的问题

最近装了ubuntu18.04 LTS,下载软件有点慢,网上搜了下解决方案,大致是两种:一、把/etc/apt/sources.list文件里的源更换一下,改成阿里云或者其它的镜像的文件;二、更换software&updates里的select best server。

一、更换/etc/apt/sources.list文件里的源

1. 备份源列表

Ubuntu配置的默认源并不是国内的服务器,下载更新软件都比较慢。首先备份源列表文件sources.list:

# 首先备份源列表
sudo cp /etc/apt/sources.list /etc/apt/sources.list_backup

2. 打开sources.list文件修改

选择合适的源,替换原文件的内容,保存编辑好的文件, 以阿里云更新服务器为例(可以分别测试阿里云、清华、中科大、163源的速度,选择最快的):

# 打开sources.list文件
sudo gedit /etc/apt/sources.list

编辑/etc/apt/sources.list文件, 在文件最前面添加阿里云镜像源:

#  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 main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates 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

3. 刷新列表

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install build-essential

下载速度瞬间就起飞了。

4. 其他源
