ubuntu添加阿里源 失败

天星远

环境 ubuntu 19.04

日期2020/04/18

 

更新软件失败，以为是源的问题 ，所以尝试 修改 源为 国内阿里源

查看 系统版本

lsb_release -a
No LSB modules are available.
Distributor ID:    Ubuntu
Description:    Ubuntu 19.04
Release:    19.04
Codename:    disco

其中的codename是这个版本的系统别名

查看阿里源

http://mirrors.aliyun.com/ubuntu/dists/

发现如下内容，以为支持，所以更换阿里源

disco/                                             14-Apr-2020 20:23                   -
disco-backports/                                   14-Apr-2020 20:24                   -
disco-proposed/                                    14-Apr-2020 20:24                   -
disco-security/                                    14-Apr-2020 20:24                   -
disco-updates/                                     14-Apr-2020 20:23                   -

结果报错，阿里源 也不是所有版本都支持

19.04这个版本 已经不支持了，所以更改，源文件的地址为 
deb http://cn.archive.ubuntu.com/ubuntu/
deb http://old-releases.ubuntu.com/ubuntu/

之后 sudo apt update,就可以正常使用了。
