What is .mamba_trash and how to remove it?

Question

after I remove a micromamba environment by

micromamba env remove -n <env-name>

I run

micromamba env list

It shows an "environment" called

<the removed env-name>.mamba_trash

What is it, how can I get rid of it? I didn't find any instructions in the mamba documentation.

Answer 1

They can be removed with

micromamba clean --trash

From micromamba clean --help:

  --trash                     Remove *.mamba_trash files from all environments
