UnavailableInvalidChannel: The channel is not accessible or is invalid. error code: 403, conda-forge not working

my conda-forge is not working and displaying the following error even while creating a new enviornment:
(base) C:\Users\1836849\Documents\GitHub_Repository\ChemOS-master>conda create -n py36 python=3.6
Collecting package metadata (current_repodata.json): failed
UnavailableInvalidChannel: The channel is not accessible or is invalid.

You will need to adjust your conda configuration to proceed.
Use `conda config --show channels` to view your configuration's current state,
and use `conda config --show-sources` to view config file locations.

what is the possible solution?

As per documentation here there are a few possible reasons for receiving this error:
The user has misconfigured their channels in their configuration (for example, the secure location where the token is stored was accidentally deleted (most common)
A firewall or other security device or system is preventing user access (second most common)
They are blocking their access because of a potential terms of service violation (third most common)
Solution
First, run the following to undo your configuration of Commercial Edition:
conda config --remove-key default_channels
Next, install or upgrade the conda-token tool:
conda install --freeze-installed conda-token
Lastly, re-apply the token and configuration settings:
# Replace <TOKEN> with your token
conda token set <TOKEN>

Anaconda version update not working (Windows)

Just tried to update conda via Anaconda Prompt but it is not working.
After I managed to open Anaconda Prompt as administrator to mitigate:The current user does not have write permissions to a required path. problem even if I open promt from navigator-Enviroments-base root - open terminal
after command conda update conda.
So After opening Prompt as Administrator I used commands from conda cheatlist from here:https://conda.io/projects/conda/en/latest/user-guide/cheatsheet.html
I have updated Anaconda but when I ask version number it the same before updating.
I typed: conda update conda
I got:

Any ideas what I should try to properly update Anaconda and Navigator from the prompt?
Or I have to download New Version from the website and Uninstall old one?
Many Thanks!

You may want to run:
conda update conda
conda install anaconda=<version>

I have tried many ways, this below one worked for me
the (base) in anaconda file has no environment variable set.
you can know what envs is set by typing
"conda info"
if it shows
-active environment : none-
then,
create a new envs as below
conda create --name environment_name_of_your_own
after following the steps
conda activate environment_name_of_your_own
from (base) , it changes to (environment_name_of_your_own)
you can run your commands from here now, it will work mostly.
it worked for me.

"Collecting package metadata: failed" with UnavailableInvalidChannel error when conda install in a brand new Anaconda environment

Just after I successfully installed Anaconda in Windows (using the official installer), I tried to install a package with conda command. Then, I got the following UnavailableInvalidChannel error:
C:\Users\user>conda install numpy
WARNING: The conda.compat module is deprecated and will be removed in a future release.
Collecting package metadata: failed
UnavailableInvalidChannel: The channel is not accessible or is invalid.
channel name: pkgs/msys2/repo.anaconda.com/pkgs
channel url: https://repo.anaconda.com/pkgs/msys2/repo.anaconda.com/pkgs

It seems conda is using wrong channel url, but there is no reference to https://repo.anaconda.com/pkgs/msys2/repo.anaconda.com/pkgs in my config.
C:\Users\user>conda config --show channels
channels:
- https://repo.anaconda.com/pkgs/

Do you have any idea how to resolve this problem?

Installing local packages with Anaconda

I am using Anaconda with 64 bit Python 2.7 on a Windows 7 machine that is necessarily isolated from the internet. I am having difficulty installing local packages. Right now I am stuck on PyMySQL, but I imagine I would also have the same problem with other packages. My system PATH variable has Anaconda at the beginning.
Trying a path to the unpacked folder:
conda install –-offline c:\temp\PyMySQL-master\pymysql
PackageNotFoundError: Package missing in current win-64 channels:
- c:\temp\pymysql-master\pymysql
What does this error mean? I have tried using a tar file and I get the same error message. This is the same message I get if I spell the filename wrong, so there is something I am missing to get it to recognize the file. Do I need to create a channel for a local package? How would I do that? Is there anything else I should try?
Here is the response in verbose mode:
conda install --offline --verbose c:\temp\pymysql.tar

Every conda package ever built to date has a .tar.bz2 extension, and this assumption is baked in deeply. Someday we'll probably add different package types, compression algorithms, and extensions, but that's a ways off. So to work, your command needs to be
conda install --offline --verbose c:\temp\pymysql.tar.bz2
and pymysql.tar.bz2 needs to be a real conda package. (i.e. if you unpack that tarball and there's no info/files file in it, then it's not a conda package)
