2.6.0+dfsg-6 is actually released in pytorch-cuda since it contains
changes atop dfsg-5. For this case, we can use dfsg-7 on both sides,
since the source of cuda version is the same as the cpu version.
Mo has been using this versioning scheme since the first upload of
-cuda (and other variants) packages.

Thanks,
