Ubuntu 20.04 has been released for a while, its code is Focal Fossa. Again, if you are in China, better change the update source to mirror sites.

This post is just a copy from Change Ubuntu 18.04 update source to mirror site in China, and I just replaced the source url from thoes ones of 18.04 to 20.04

Here are several famous mirror sites. What you need todo is pick one from below and edit etc/apt/sources.list, replace the content in this file.

There are some links beend commented out.

starts withdeb-src is for source code, without them the speed would be even faster
the one with focal-proposed are just proposed updates, only enable them if you know the risk.

Better backup you etc/apt/sources.list before you do this
