conda install python=3.6 ends in Solving environment: failed even though conflict has a relevant dependency

[BE-Bob]

Current Behavior

In a conda environment, I am attempting to upgrade python from 3.5.6 to 3.6*. I issue the command
conda install python=3.6
and it fails with a "Solving environment: failed" and reference to a package that is installed.
I tried the following:
updating conda to 4.5.11 (in the base environment)
conda update conda
updating all in environment
conda update --all
The result is still the same error.

Steps to Reproduce

conda install python=3.6
Solving environment: failed

UnsatisfiableError: The following specifications were found to be in conflict:
  - nb_anacondacloud==1.4.0=py35_0 -> python=3.5
  - python=3.6
Use "conda info <package>" to see the dependencies for each package.

I checked to see if nb_anacondacloud has a version compatible with python 3.6 and it does.

conda info nb_anacondacloud

Expected Behavior

I get an error even though it seems that conda should be able to figure out that it has to update all of the dependencies in the environment.

I had a similar issue, and I changed the owner of the folder which has anacond3, and that resolved the issue. I tried to install different packages.
sudo chown -R MY_USER_NAME /usr/local/bin/anaconda3
