修改 WSL Ubuntu 18.04 默认源为阿里云镜像

Win10 Windows Store 中下载的 WSL Ubuntu 18.04 默认的源 apt install 下载速度异常缓慢,想替换成国内阿里云的镜像源。

 

确认默认源

首先查看默认的源的地址

sudo vim /etc/apt/sources.list

# See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to
# newer versions of the distribution.
deb http://archive.ubuntu.com/ubuntu/ bionic main restricted
# deb-src http://archive.ubuntu.com/ubuntu/ bionic main restricted

## Major bug fix updates produced after the final release of the
## distribution.
deb http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted
# deb-src http://archive.ubuntu.com/ubuntu/ bionic-updates main restricted

## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu

deb http://archive.ubuntu.com/ubuntu/ bionic universe
# deb-src http://archive.ubuntu.com/ubuntu/ bionic universe
deb http://archive.ubuntu.com/ubuntu/ bionic-updates universe
# deb-src http://archive.ubuntu.com/ubuntu/ bionic-updates universe

修改默认源

首先将原配置文件备份

sudo cp /etc/apt/sources.list /etc/apt/sources.list.20181013

然后 VIM 打开,替换

:%s/security.ubuntu/mirrors.aliyun/g
:%s/archive.ubuntu/mirrors.aliyun/g

更新

sudo apt update

再使用 apt install 速度就快多了
