Conda update conda issue

[Elango v]

We have python2.7 installed using miniconda. And then created py36 env with python3.6. Everything is working fine for last few years.

We usually use pip to install all the packages. 

Recently I tried to install a package using conda. I got below error message,

error message: "CondaMultiError: RemoveError: 'setuptools' is a dependency of conda and cannot be removed from

conda's operating environment."

To resolve this error message I tried to upgrade conda using below command

 sudo /usr/share/miniconda2/bin/conda update --force conda

 

 This resulted in below error message also unistalled many pacakges including pip and features and a lot of other

 ERROR conda.core.link:_execute(637): An error occurred while installing package 'None'.

AssertionError()

Attempting to roll back.

Rolling back transaction: done

CondaMultiError: AssertionError()

()

AssertionError()

After this command if I run any simple commands like conda list I am getting below error message

sudo /usr/share/miniconda2/bin/conda install conda

Traceback (most recent call last):

  File "/usr/share/miniconda2/bin/conda", line 13, in <module>

    sys.exit(main())

    from concurrent.futures import ProcessPoolExecutor, ThreadPoolExecutor, Executor, Future, _base, as_completed  # NOQA

ImportError: No module named concurrent.futures

As pip is not available now, I am unable to install futures pkg now. How to resolve this? Please advise.
