Ubuntu exchanges Ali source through the terminal command line (incidentally solve the problem of outdated version of ubuntu)

1. Check the Codename of the Ubuntu system

$ lsb_release -a

got the answer:

No LSB modules are available.
Distributor ID: Ubuntu
Description:    Ubuntu 17.10
Release:        17.10
Codename:       artful

Visit http://mirrors.aliyun.com/ubuntu/dists/ to see if Aliyuan supports

Modify sources.list

$ sudo vi /etc/apt/sources.list

Delete the sources.listoriginal content and replace it with Aliyuan

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

deb http://mirrors.aliyun.com/ubuntu/ artful-proposed main restricted universe multiverse
deb-src http://mirrors.aliyun.com/ubuntu/ artful-proposed main restricted universe multiverse

Note that the artful of each line here needs to correspond to the Codename of the system, so the sources.listfiles between different system versions cannot be universal

         Pay attention to version 17.10 . Although you can see it in http://mirrors.aliyun.com/ubuntu/dists/ , it is actually not usable.

The reason is that the non-mainstream version such as 17.10 is no longer supported. The solution is to look at the link . In simple terms, you need to change the domain name to  old-releases.ubuntu.com
