When trying to upgrade my anaconda distribution I keep getting the following error:

Collecting package metadata (repodata.json): done
Solving environment: failed

PackagesNotFoundError: The following packages are not available from current channels:

  - pkgs/free/win-64::anaconda==4.4.0=np112py36_0 -> bzip2==1.0.6=vc14_3
  - pkgs/free/win-64::anaconda==4.4.0=np112py36_0 -> cryptography==1.8.1=py36_0
    [loads of similarly cryptic packages names]
  - pkgs/free/win-64::anaconda==4.4.0=np112py36_0 -> vs2015_runtime==14.0.25123=0

Current channels:

  - https://repo.anaconda.com/pkgs/main/win-64
  - https://repo.anaconda.com/pkgs/main/noarch
  - https://repo.anaconda.com/pkgs/r/win-64
  - https://repo.anaconda.com/pkgs/r/noarch
  - https://repo.anaconda.com/pkgs/msys2/win-64
  - https://repo.anaconda.com/pkgs/msys2/noarch
  - https://conda.anaconda.org/conda-forge/win-64
  - https://conda.anaconda.org/conda-forge/noarch

To search for alternate channels that may provide the conda package you're
looking for, navigate to

    https://anaconda.org

and use the search bar at the top of the page.

This is raised no matter what or how I try to install/update: It is raised both with conda update --all and conda update numpy or any other package I tried, so this should not be due to some specific package that is not in the channel.

It is even raised when I try to update anaconda itself by conda update -n root conda.

I have tried updating numpy from Anaconda navigator.

Because of this question I added conda-forge to my channels - to no avail. Grateful for any help.

EDIT: I finally solved this by completely removing and reinstalling Anaconda3, but I still lack an understanding of what exactly has originally caused the problem.

    The error references [the **free** channel](https://docs.conda.io/projects/conda/en/latest/user-guide/configuration/free-channel.html). Perhaps try temporarily enabling searching the **free** channel. That is, `conda config --set restore_free_channel true`, and then retry the updating/installing. – merv Jun 17 '20 at 19:21
  • @merv this does change something, but does not leave me at any clearer idea of what the actual problem is and what I have to do now: The new message is ```The environment is inconsistent, please check the package plan carefully The following packages are causing the inconsistency:``` where it lists anaconda, matplotlib, scikit-image and seaborn. And after that prompt just seems to kill itself, not even reacting to Ctrl-C... – Dididombi Jun 18 '20 at 06:54
