Troubleshooting docs

  • My problem is not solved in the Troubleshooting docs

Anaconda default channels

  • I do NOT use the Anaconda default channels (pkgs/* etc.)

How did you install Mamba?

Mambaforge or latest Miniforge

Search tried in issue tracker

envs_dirs crash

Latest version of Mamba

  • My problem is not solved with the latest version

Tried in Conda?

I do not have this problem with Conda, just with Mamba

Describe your issue

Another deviation from mamba v1 -> v2.

The following crashes mamba 2, but works fine in mamba 1.

mkdir -p /tmp/envroot/envs && \
   chmod 0 /tmp/envroot/envs && \
   CONDA_ENVS_DIRS=/tmp/envroot/envs micromamba create -n test132

...
critical libmamba filesystem error: status: Permission denied [/tmp/envroot/envs/test132]
info     libmamba ****************** Backtrace End ********************

I'll work up a PR for this soon.
