mamba init fails during compass conda environment setup

[trhille]

On Perlmutter, I get the following error when I execute ./conda/configure_compass_env.py --conda ~/miniconda3 -m pm-cpu --with_albany :

Traceback (most recent call last):
  File "/global/cfs/cdirs/piscees/trhille/compass/./conda/configure_compass_env.py", line 120, in <module>

I tried executing each of the commands in the error, and the issue appears to be the mamba init command:

'Namespace' object has no attribute 'no_user'

I changed https://github.com/MPAS-Dev/compass/blob/main/conda/shared.py#L179 from mamba init to conda init and was able to successfully create dev_compass_1.2.0-alpha.4

I should note that I got the same error when I pointed the --conda flag at my mambaforge install.

This appears to be an incompatibility between the latest conda and anything but the latest mamba. Something like:

source ~/mambaforge/etc/profile.d/conda.sh
source ~/mambaforge/etc/profile.d/mamba.sh
mamba activate
mamba remove -y boa
mamba update mamba

should fix it. Then, rerun ./conda/configure...

I can try to add this to compass itself later today.
