Shulou(Shulou.com)06/02 Report--

This article mainly explains how to change Ubuntu 20.04 to Ali source, the content is clear, interested friends can learn, I believe it will be helpful after reading it.

Note that this article is not simply to teach you how to switch to 20.04 sources, but to teach you a way to switch sources based on 20.04.

At the time of writing this article, the author has not yet released the official version of release, but can already see the active existence in the warehouse, so I wrote this article.

Please note that the official version of Ubuntu 20.04 was released on April 23.

Please note: it is found that some software, such as ckermit, are not available in the warehouse, upgrade and source change at your own discretion.

1 back up the original source

Cp-ra / etc/apt/sources.list / etc/apt/sources.list.bak

2 find out the code name of ubuntu, such as:

4.10Warty Warthog (warthog with warts)

5.04Hoary Hedgehog (gray hedgehog)

5.10Breezy Badger (vivacious badger)

...

To know the code name of the current system, use the following command:

Lsb_release-a

3 go to Aliyuan to see if this source exists.

Http://archive.ubuntu.com/ubuntu/dists/

As you can see, there is now a source for ubuntu 20.04 (code name focal).

4 then use the following as the template to replace the place of 'TODO'' with the Codename above

Deb http://mirrors.aliyun.com/ubuntu/ TODO main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ TODO main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ TODO-security main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ TODO-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ TODO-updates main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ TODO-updates main restricted universe multiversedeb http:/ / mirrors.aliyun.com/ubuntu/ TODO-proposed main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ TODO-proposed main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ TODO-backports main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ TODO-backports main restricted universe multiverse

For example, after I changed the source of 20.04, it was like this:

Deb http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ focal main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ focal-security main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ focal-updates main restricted universe multiversedeb http:/ / mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ focal-proposed main restricted universe multiversedeb http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiversedeb-src http://mirrors.aliyun.com/ubuntu/ focal-backports main restricted universe multiverse

Then paste it into / etc/apt/sources.list just now.
