Thanks, Kacper & Nathan --

UnsatisfiableError: The following specifications were found to be in conflict:
  - cyglfw3 -> python 3.5* -> openssl 1.0.1*
  - cyglfw3 -> python 3.5* -> xz 5.0.5
  - python 3.6*
Use "conda info <package>" to see the dependencies for each package.

​'conda info cyglfw3' finds the package missing from linux-64 channels.

From the unsatisfiable error, i don't really understand the best course of action. It would seem at this point that cyglfw3 has bindings for python3.5, but not yet for python3.6 -- is that the upshot?

I don't know what's required to generate the updated bindings. The 'yt' install was done using this same procedure:
conda install -c http://use.yt/with-conda yt

The versions are openssl is 1.0.2, and xz 5.2.2-1
​Thanks,
~ E.m​

Hi,
I uploaded the missing packages. Please try again.
Cheers,
