Describe your issue

Hi all,

I opened this issue on the setup-micromamba repo yesterday and got redirected here.
Simply put, when creating an environment with micromamba from a conda-lock.yml file, there is an error when trying to extract one of the packages.
In my original issue, in CI it always seems to fail on the very first package.
I tried to reproduce the same issue by running micromamba create -f conda-lock.yml -n brains2 in a fresh docker container (either mambaorg/micromamba or a ubuntu:latest image with micromamba installed the classic way), and similar errors occurred, although on other packages further down the list.

Note that I am able to properly create the environment from the conda-lock.yml file with conda-lock install and the errors only occur with micromamba create.

Thanks for your input

This seems to be working with the last commit on main.
2.0.7.rc0 (and followed shortly by 2.0.7) contains the fix (#3710).
Please try it out to confirm.
Thanks!

To complete @Hind-M's remark, you can try it with setup-micromamba using in the action:

micromamba-version: 2.0.7.rc0
