AssertionError while updating conda

I've tried to update conda using the following command :

~$ conda update conda

It outputs the following message:

WARNING conda.base.context:use_only_tar_bz2(632): Conda is constrained to only 
using the old .tar.bz2 file format because you have conda-build installed, 
and it is <3.18.3.  Update or remove conda-build to get smaller downloads 
and faster extractions.
Collecting package metadata (repodata.json): done
Solving environment: - 

The environment is inconsistent, please check the package plan carefully

The following packages are causing the inconsistency:

- defaults/linux-64::cytoolz==0.9.0.1=py37h14c3975_1

- and around 100 more

I have also tried 

~$ conda update --all

but it gave me the same error as before.

I had the same error, and I use miniconda, so I don't want to install anaconda. It worked for me to update python from 3.6 to 3.7 as follows:

$ conda install python=3.7

When I did this, conda updated automatically to the latest version.

The commands made me fail to conda install packages,lead to "'setuptools' is a dependency of conda and cannot be removed from conda's operating environment."

conda install tensorflow-gpu==1.9.0
pip install setuptools==38.6.0

then I try those ...

conda update -f conda
conda install -f codna

The second line help me solve the problem. I'm forwardly looking for the why.

Regarding this matter i have found a solution that is not well explained but solve the problem:

first : using the command :

~$ conda install anaconda

this resolve the problem of the environment inconsistency .

second : using the command:

 ~$ conda update conda

the command will be executed with no problems and conda will be updated proberly.
