[New-bugs-announce] [issue43992] Unable to get external dependencies for CPython on Ubuntu Linux 20.04.1

[Shreyan Avigyan]

New submission from Shreyan Avigyan <shreyan.avigyan at gmail.com>:

I'm trying to build CPython on Ubuntu but I can't get the external dependencies. Running this command :-

$ sudo apt-get build-dep python3

gives the output :-

Reading package lists... Done
E: You must put some 'deb-src' URIs in your sources.list

What is the exact string to add to /etc/apt/sources.list?

System Info: Ubuntu 20.04.1 (Focal Fossa)
Architecture: x64
GCC version: 9.3.0

(I've posted the problem in this issue tracker because Google and Stack Overflow doesn't seem to have an answer. I'm sorry for posting this here but no one seem to have the answer to this apart from core or experienced developers.)
