I was able to update the Anaconda version to the latest 4.3.0 by running the following command, but the python version remains 3.5 and not updated to 3.6. (Only updated from python3.5.x to python3.5.y)
$ conda update conda
$ conda update --all
I tried to install python3.6 by specifying the version, but I cannot install it with the following error.
$ conda install python=3.6

Uninstall the package that is causing the error. (Is it related to notebook from the name?)

The deleted nb_ * package seemed to be related to notebook, but it didn't exist in the environment where Anaconda 4.3.0 was newly installed, so I decided that it would be okay to delete it.
