Linux ubuntu 切換阿里更新源

如國內網路使用ubuntu 則會出現apt-get無法安裝更新的問題,這時大家需要切換到一些國內第三方更新源。

  1. 首先檢視自己的ubuntu系統的codename,直接導致你更新的源是否對你的系統起效果,檢視方法: lsb_release -a
    這裡寫圖片描述
    我的系統顯示:Codename: bionic
  2. 確認阿里源支援
    登陸以下網頁:http://mirrors.aliyun.com/ubuntu/dists/
    該網頁顯示了阿里雲支援的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)

  3. 備份系統源:
    cd /etc/apt
    sudo mv sources.list sources.list_bak

  4. 新增新的原始檔:sudo vi sources.list
    並新增以下內容:注意,每一行的trusty應該用第一步檢視得到的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-proposed 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

  5. 儲存並且sudo apt-get update,更新成功
