Linux 换源方法

---

通用方法

• 换国内源，最直接的就是上阿里、中科大的镜像官网。
  • 阿里Mirror
  • 中科大Mirror

• 根据选择自己的Linux发行版，点帮助help就有详细了，复制到sources.list，更新下源就好了。

Ubuntu换国内源

Xubunut、Kubuntu都是ubuntu发行版，只是桌面环境不同，换源也是一样。

1. sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak 备份原来的sorce文件
2. sudo gedit /etc/apt/sources.list 修改sources.list文件

gedit是ubuntu自带的图像界面编辑器，xubuntu、kubuntu自带的不是gedit，Kubuntu自带kate。你也可以用vi/vim去编辑。
sudo vim /etc/apt/sources.list

3. 添加阿里、中科大镜像源

# 阿里镜像源
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-updates main restricted universe multiverse
deb https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse
deb-src https://mirrors.ustc.edu.cn/ubuntu/ bionic-backports main restricted universe multiverse

# 中科大镜像源

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-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

将上面的镜像源覆盖到sources.list里，保存。

4. sudo apt-get update 更新源

Deepin换国内源

1. sudo cp /etc/apt/sources.list /etc/apt/sources.list.bak 备份原来的sorce文件
2. sudo deepin-editor /etc/apt/sources.list 修改sources.list文件

deepin-editor是deepin自带的图像界面编辑器，和ubuntu的gedit一样。你也可以用vim去编辑。看自己嘛。

3. 更换为阿里或者中科大的镜像源

• 阿里

# aliyun
deb [by-hash=force] http://mirrors.aliyun.com/deepin panda main contrib non-free
#deb-src http://mirrors.aliyun.com/deepin panda main contrib non-free

• 中科大

# ustc
deb [by-hash=force] http://mirrors.ustc.edu.cn/deepin panda main contrib non-free
#deb-src http://mirrors.ustc.edu.cn/deepin panda main contrib non-free

将上面的一个镜像源 覆盖 到sources.list里，保存。

4. sudo apt-get update 更新源
   4.1 如果出现lock报错，删除lock文件就好了
