Where is the code downloaded by apt source stored?

Question

I know how to use apt source but where are the files of apt source stored?

Answer 1

They are located in same directory as their corresponding deb files, use --print-uris to get a list of links related to the package source and patch:

apt-get source pkg --print-uris

And as others mentioned after downloading the source it will be placed in same directory where you ran the command.
