### Issue

This concerns a fresh installation on Windows OS 10.0.22000 N/A Build 22000 x64.

When using the ~[Miniforge-pypy3-Windows-x86_64](https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge-pypy3-Windows-x86_64.exe)~ [Miniforge3-Windows-x86_64](https://github.com/conda-forge/miniforge/releases/latest/download/Miniforge3-Windows-x86_64.exe) installation, for some reason the package cache default path is assigned to `\\server\share\conda\pkgs`, which then throws the following error whenever I try to do `conda update` or `conda create` commands:

`NotWritableError: The current user does not have write permissions to a required path. path: \\server\share\conda\pkgs\urls.txt`

When I use `conda config --show pkgs_dirs`, I get the following list:
- \\server\share\conda\pkgs
- C:\Users\username\miniconda3\pkgs

Hence I ran `conda config —add pkgs_dirs C:\Users\username\miniconda3\pkgs` which pushed the latter path to the top of the list. From thereon, my conda installation is now working and I can create environments as per normal.

I had the same issue with [miniconda](https://docs.conda.io/en/latest/miniconda.html). The SHA256 checksum was correct.
