What happened?

I'm moving an env in an attempt to create an offline system backup or system transfer. Issue is occurring when trying to transfer it to a test unit. Please see the attached screenshot.

After some testing it's one of the following packages causing the error.

colorama=0.4.6=pypi_0
ffmpeg-python=0.2.0=pypi_0
filelock=3.8.0=pypi_0
future=0.18.2=pypi_0

ffmpeg-python=0.2.0=pypi_0
more-itertools=9.0.0=pypi_0
pyyaml=6.0=pypi_0
regex=2022.9.13=pypi_0

There is a conflict in one of these four.

I can confirm that these PermissionErrors still exist in the latest conda version 23.1.0 running on windows 10 22H2.
In my case it failed to patch the prefix of a .pyd file of wrapt in the site packages folder of the environment I tried to unpack. The issue is also reproducible (with the same file being affected) on dedicated windows CI nodes that do not use any "file monitoring" solutions, which is usually a good candidate for these kinds of problems.

What @vickorian and I have in common is that we try to use conda-unpack.exe. So I tried the documented alternative conda-unpack-script.py with the interpeter that is part of the env I'm trying to unpack. Same problem. Then I used the script but with an independent python interpreter - and it worked reliably.

Hypothesis

The conda-unpack.exe uses the interpreter that is part of the environment to be patched. In other words, the environment is used to patch itself. Maybe that is just a bad idea in general and the robust way is to always use an independent interpreter to perform this job.

@axel-kah your solution works.
Use the interpreter of base environment to run the <env name>/Script/conda-unpack-script.py script.
Thanks.

[btsai-dev]

I also second @ZhiZe-ZG's comment.

Specifically, running python <env name>/Scripts/conda-unpack-script.py as described in the directory above the environment name. Running python Scripts/conda-unpack-script.py from within the environment folder still resulted in permission errors.
