|
> 因为Ubuntu自带的源已经老旧，下载速度慢，而且不稳定-
|
||
|
|
> 本教程告诉大家如何更换Ubuntu源到国内几个比较好的源
|
||
|
|
|
||
|
|
更换源步骤如下：
|
||
|
|
|
||
|
|
1. 备份源列表
|
||
|
|
|
||
|
|
`sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak`
|
||
|
|
|
||
|
|
2. 命令行打开sources.list文件
|
||
|
|
|
||
|
|
`sudo gedit /etc/apt/sources.list`
|
||
|
|
|
||
|
|
3. 修改sources,list文件【本例更改为阿里镜像源】
|
||
|
|
|
||
|
|
# 阿里镜像源
|
||
|
|
|
||
|
|
```bash
|
||
|
|
deb http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
|
||
|
|
deb-src http://mirrors.aliyun.com/ubuntu/ bionic main restricted universe multiverse
|
||
|
|
|
||
|
|
deb http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
|
||
|
|
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-security main restricted universe multiverse
|
||
|
|
|
||
|
|
deb http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
|
||
|
|
deb-src http://mirrors.aliyun.com/ubuntu/ bionic-updates main restricted universe multiverse
|
||
|
|
|
||
|
|
deb http://mirrors.aliyun.com/ubuntu/ bionic-proposed main restricted universe multiverse
|
||
|
|
deb-src 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-backports main restricted universe multiverse
|
||
|
|
```
|
||
|
|
|
||
|
|
4. 更新并升级
|
||
|
|
|
||
|
|
`sudo apt-get update && sudo apt-get upgrade`
|
||
|
|
|
||
|
|
5. 等待更新并升级完成即可
|
||
|
|
|
||
|
|
【注意】更新过程中可能会有询问是否下载包的提示，输入y，按回车即可。
|
||
|
|
|
||
|
|
【注意！注意！注意】更新时一定要把Linux的网络连接检查是否已经连接上网络，不然会出错，我之前试一直不成功，困了好久，才发现是虚拟机的网络没有连接。。。
|
||
|
|
|
||
|
|
更新好后就可以用命令行进行安装软件或者插件了
|
||
