Now I have 2 issues that stop my work.
1) I cannot use conda installfor any package.
It will give me the error in solving environmentlist this:
现在我有两个问题阻止了我的工作。1) 我不能conda install用于任何包裹。它会给我solving environment列表中的错误：
failed with initial frozen solve. Retrying with flexible solve.
then it will fail again and give message like this:
然后它将再次失败并给出如下消息：
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.
即使在检查了不兼容的包之后，它也没有给我解决方案。
2) When I want to upgrade or downgrade conda by the command:
2) 当我想通过命令升级或降级 conda 时：
conda update -n base conda
or
或者
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.
它会在 中再次给我错误solving environment，我认为这与第一个问题有关。
Now I cannot use conda for anything, please advise and thank you!
现在我不能使用 conda 做任何事情，请指教，谢谢！

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.
我遇到了同样的问题，但找不到解决方案，但我确实找到了解决方法。如果您创建一个 env 并激活该 env 然后进行安装，它似乎工作得很好。如果您不需要很多图书馆，我会尝试这样做。
Commands are:
命令是：
- Create env
- 创建环境
conda create --name myenv
- Activate the env
- 激活环境
conda activate myenv

You may downgrade to an older version of conda 4.6.14 and then install your packages.
您可以降级到 conda 4.6.14 的旧版本，然后安装您的软件包。
conda config --set allow_conda_downgrades true
conda install conda=4.6.14

Create a new environment if your are not superuser, after that activate environment to install packages
如果您不是超级用户，请创建一个新环境，然后激活环境以安装软件包

If your conda version is greater than or equal to 4.8, you may see that error.
如果您的 conda 版本大于或等于 4.8，您可能会看到该错误。
(base) [localhost ~]$ conda --version
conda 4.8.2
(base) [localhost ~]$ conda install -c anaconda requests-kerberos
Collecting package metadata (current_repodata.json): done
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
如果可能，请使用以下命令降级您的 conda
conda config --set allow_conda_downgrades true
conda install conda=4.6.14
Then create your virtual environment:
然后创建您的虚拟环境：
conda create --name myenv_conda
Then activate your myenv_conda
然后激活你的 myenv_conda
conda activate myenv_conda
Now try to install packages using conda -c install anaconda
现在尝试使用 conda -c install anaconda 安装软件包
eg: conda install -c conda requests-kerberos
output:
(myenv_conda) [localhost ~]$ conda install -c anaconda requests-kerberos
Collecting package metadata: done
Solving environment: done
