[SOLVED] apt-get source atlas

[ACluk90]

Hi

I am trying to get the source code of libatlas, the "Automatically Tuned Linear Algebra Software".
I tried doing so using "sudo apt-get source atlas", resulting in the error message "E: Unable to find a source package for atlas".
I also tried "apt-get source blas", resulting in the same error.

Does anyone have an idea what's wrong?

Thank you.

solved by copying all lines in /etc/apt/sources.list, replacing deb with deb-src on the copied lines.
