python-pyliblzma is not a package in Ubuntu. The version number indicates it was probably a package from a PPA somewhere.
It's conflicting with python-lzma, which *is* a package in Ubuntu, and the correct package name to provide lzma.so.
Remove python-pyliblzma, and tell that PPA's owner that they should delete it, it's clearly a problem.
