Docker切換到阿里雲

 

1. 首先查看自己的ubuntu系統的codename，直接導致你更新的源是否對你的系統起效果，查看方法： lsb_release -a

我的系統顯示：Codename: bionic

1. 確認阿里源支持

登陸以下網頁：http://mirrors.aliyun.com/ubuntu/dists/

該網頁顯示了阿里雲支持的ubuntu系統下各個Codename版本，確保自己的Codename在該網頁中存在（一般都會有的）

1. 備份系統源：

cd /etc/apt sudo mv sources.list sources.list_bak

 

添加新的源文件：

sudo vi sources.list

並添加以下內容：注意，每一行的trusty應該用第一步查看得到的Codename來代替

deb http://mirrors.aliyun.com/ubuntu/ trusty main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-backports main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-proposed main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-security main multiverse restricted universe
deb http://mirrors.aliyun.com/ubuntu/ trusty-updates main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty main multiverse restricted universe
deb-src http://mirrors.aliyun.com/ubuntu/ trusty-backports main multiverse restricted universe

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

 

保存並且 sudo apt-get update， 更新成功
