I am using anaconda as below:
(base) C:\Users\xxx>conda info
active environment : base
active env location : C:\Users\xxx\Documents\ANACONDA
shell level : 1
user config file : C:\Users\xxx\.condarc
populated config files : C:\Users\xxx\.condarc
conda version : 4.7.11
conda-build version : 3.18.9
python version : 3.6.9.final.0
virtual packages :
base environment : C:\Users\xxx\Documents\ANACONDA (writable)
channel URLs :
package cache : C:\Users\xxx\Documents\ANACONDA\pkgs
C:\Users\xxx\.conda\pkgs
C:\Users\xxx\AppData\Local\conda\conda\pkgs
envs directories : C:\Users\xxx\Documents\ANACONDA\envs
C:\Users\xxx\.conda\envs
C:\Users\xxx\AppData\Local\conda\conda\envs
platform : win-64
user-agent : conda/4.7.11 requests/2.22.0 CPython/3.6.9 Windows/10 Windows/10.0.16299
administrator : False
netrc file : None
offline mode : False
Now I have 2 issues that stop my work.
1) I cannot use conda install for any package.
It will give me the error in solving environment list this:
failed with initial frozen solve. Retrying with flexible solve.
then it will fail again and give message like this:
Found conflicts! Looking for incompatible packages.
This can take several minutes. Press CTRL-C to abort.
Even after the checking for incompatible packages, it didn't give me the solution.
2) When I want to upgrade or downgrade conda by the command:
conda update -n base conda
or
conda install conda = 4.6.11
It will give me errors again in the solving environment, and I think this is related to the first issue.
Now I cannot use conda for anything, please advise and thank you!

I ran into the same problem and I couldn't find a solution, but I did find a workaround. If you create an env and activate that env and then do the install, it seems to work just fine. If you don't need a lot of libraries I would try that.
Commands are:
- Create env
conda create --name myenv
- Activate the env
conda activate myenv
I started running in to this problem when one package suggested following modifications before installation
conda config --set channel_priority true
so I just reverted it and voila error's gone
conda config --set channel_priority false
I solved a similar problem by doing the following:
conda update --all --yes
You may downgrade to an older version of conda 4.6.14 and then install your packages.
conda config --set allow_conda_downgrades true
conda install conda=4.6.14
If your conda version is greater than or equal to 4.8, you may see that error.
(base) [localhost ~]$ conda --version
conda 4.8.2
(base) [localhost ~]$ conda install -c anaconda requests-kerberos

Solving environment: failed with initial frozen solve. Retrying with flexible solve.
Solving environment: failed with repodata from current_repodata.json, will retry with next repodata source.
Downgrade your conda if possible using the following commands
conda config --set allow_conda_downgrades true
conda install conda=4.6.14
Then create your virtual environment:
conda create --name myenv_conda
Then activate your myenv_conda
conda activate myenv_conda
Now try to install packages using conda -c install anaconda
eg: conda install -c conda requests-kerberos
output:
(myenv_conda) [localhost ~]$ conda install -c anaconda requests-kerberos
Collecting package metadata: done
Solving environment: done

helped me. Creating a new environment using the accepted answer didn't get my jupyter notebook to recognize the installed opencv. I could only import cv2 when I was in the environment on my terminal.
The fix was to use pip instead of conda, pip install opencv-python
I run into same problem while installing geopandas. The issue was gone after I upgraded to a newer version of Anaconda using:
conda update --prefix C:\apps\anaconda3 anaconda
Note: you'll have to modify the path C:\apps\anaconda3 pointing to your own installation directory.
Strangely, I did download Anaconda from the official homepage just a few hours ago and thought I had the newest version...
I had same problem but I solved because of SKİD.
After you create new env, You can run one of the codes in this link.
Create a new environment if your are not superuser, after that activate environment to install packages
Recommend to upgrade conda latest version.
conda install --quiet --yes conda=4.7.11
python -m pip install --upgrade pip==19.2.2
