Comment 4 for bug 939810

Right, this is a dependency and/or multi-arch problem.

The libssl dependency can be resolved by installing the 32-bit version: apt-get install libssl1.0.0:i386

However, the remaining unmet dependencies are not so straightforward to resolve. I don't encounter a problem with libbz2 (yet), but with libtinfo instead:

$ pypy
pypy: error while loading shared libraries: libtinfo.so.5: wrong ELF class: ELFCLASS6

However, installing libtinfo5:i386 fails, because the amd64 and i386 packages conflict with each other:

$ sudo apt-get install libtinfo5:i386
...
E: Error, pkgProblemResolver::Resolve generated breaks, this may be caused by held packages.

$ apt-cache depends libtinfo5 libtinfo5:i386
libtinfo5
  Depends: libc6
  Conflicts: libtinfo5:i386
libtinfo5:i386
  Depends: libc6:i386
  Conflicts: libtinfo5
