+ mamba install mamba=1.0.0 'python=3.10.*=*_cpython' boa --yes

Looking for: ['mamba=1.0.0', 'python=3.10[build=*_cpython]', 'boa']

Encountered problems while solving:
  - package boa-0.3.5-py36h704843e_1 requires mamba >=0.7,<0.15a0, but none of the providers can be installed

boa needs to be updated.
