Request #18196 has been accepted by diabonas [1]: Sources would still be available at https://bitbucket.org/pypy/pypy/downloads/pypy-1.9-linux.tar.bz2 / https://bitbucket.org/pypy/pypy/downloads/pypy-1.9-linux64.tar.bz2, but I don't see any package depending on this very old version 1.9 of pypy, and the current version 7.3.0 is in [community].
