same issue using parallel --jobs 3 ::: "${commands[@]}" to create 3 env in parallele.

If I use mamba: mamba env create -f my_env.yaml I get:

error    libmamba Could not set lock (Resource temporarily unavailable)
warning  libmamba Cannot lock '/home/jupyter/.conda-pkg/cache'
    Waiting for other mamba process to finish

If I use conda: conda env create -f my_env.yaml I have no error messages

mamba 1.5.3
conda 23.10.0
