篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了ubuntu 换国内最快源相关的知识,希望对你有一定的参考价值。

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:

  1.  
    # 首先备份源列表
  2.  
    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):

  1.  
    # 打开sources.list文件
  2.  
    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:

  1.  
    # 阿里源
  2.  
    deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
  3.  
    deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
  4.  
    deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
  5.  
    deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
  6.  
    deb http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse
  7.  
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
  8.  
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
  9.  
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
  10.  
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
  11.  
    deb-src http://mirrors.aliyun.com/ubuntu/ bionic-backports main restricted universe multiverse

3. 刷新列表

  1.  
    sudo apt-get update
  2.  
    sudo apt-get install build-essential

此时下载速度就明显加快了

4. 其他源

中科大源:

  1.  
    # 中科大源
  2.  
    deb https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
  3.  
    deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
  4.  
    deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
  5.  
    deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
  6.  
    deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
  7.

163源:

  1.  
    # 163源
  2.

  3.  
    deb http://mirrors.163.com/ubuntu/ bionic-security main restricted universe multiverse
  4.  
    deb http://mirrors.163.com/ubuntu/ bionic-updates main restricted universe multiverse
  5.  
    deb http://mirrors.163.com/ubuntu/ bionic-proposed main restricted universe multiverse
  6.  
    deb http://mirrors.163.com/ubuntu/ bionic-backports main restricted universe multiverse
  7.  
    deb-src http://mirrors.163.com/ubuntu/ bionic main restricted universe multiverse
  8.  
    deb-src http://mirrors.163.com/ubuntu/ bionic-security main restricted universe multiverse

  10.  
    deb-src http://mirrors.163.com/ubuntu/ bionic-proposed main restricted universe multiverse
  11.  
    deb-src http://mirrors.163.com/ubuntu/ bionic-backports main restricted universe multiverse

清华源:

  1.  
    # 清华源
  2.  
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
  3.  
    deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic main restricted universe multiverse
  4.  
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse

  11.  
    deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ bionic-proposed main restricted universe multiverse

更换sources.list速度依然还是很慢就请继续往下看第二种方法。

二、更换software&updates里的select best server

这种方法不需要改什么文件,直接在select best server里自动选择。
1. 首先按 WIN键,搜索 software,找到 software&updates.

2. 然后点进去,在 Download from里面选择 other

3. 然后点击 select best server按钮,它会找到最快的那个(最好选比较常用的源,如:清华源,阿里源或者163源之类的这样会比较稳定),然后点击 choose server,就选好镜像啦.

5. 然后在terminal里面输入

sudo apt-get update

看看是不是已经加速了呀!
