We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
conda raises bogus NotWritableError exception for a bogus attempt to chown to root
This isn't a dupe (well it is a dupe of #7109) but the issue still persists.

#7180 fixed the problem in one section of code, but the same problematic snippet is present here:

https://github.com/conda/conda/blob/master/conda/gateways/disk/update.py#L121
