Bug#810781: nvidia-cuda-toolkit : Depends: nvidia-cuda-dev (= 6.5.19-2) but it is not going to be installed

[Alex Andreotti]

Source: nvidia-cuda-toolkit
Severity: normal

Dear Maintainer,

  * What led up to the situation?

I'm trying to enable GPU rendering for blender, I had it working few weeks ago
on a very similar, almost equal, system environment (Debian/unstable),
but it was on x86 arch and I had to switch to amd64, now can't get it working anymore.

   * What exactly did you do (or not do) that was effective (or
     ineffective)?
   * What was the outcome of this action?
   * What outcome did you expect instead?

Being able to install nvidia-cuda-toolkit, it should enable GPU option in blender
(User settings -> system -> Compute device)

-- System Information:
Debian Release: stretch/sid
  APT prefers unstable
  APT policy: (500, 'unstable'), (1, 'experimental')
Architecture: amd64 (x86_64)

Kernel: Linux 4.3.0-1-amd64 (SMP w/4 CPU cores)
Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8)
Shell: /bin/sh linked to /bin/dash
Init: systemd (via /run/systemd/system)

Below the current installation error log, this morning I just upgraded because have seen
there was some *nvidia* upgrade, before the upgrade I had a different error,
but always related to unmet dependencies for nvidia-cuda-dev
