python version compatibility problem

[gpetty]

On the main repository page, there is the statement, "supports all modern versions of Python 3.9, 3.8, 3.7 ..."

But when I try to install using conda install -c conda-forge cfgrib, I get the following error:

UnsatisfiableError: The following specifications were found
to be incompatible with the existing python installation in your environment:

Specifications:

• cfgrib -> python[version='3.6.12|3.6.12|3.7.10|3.7.10|>=2.7,!=3.0.,!=3.1.,!=3.2.,!=3.3.,!=3.4.*|>=3.7,<3.8.0a0|>=3.6,<3.7.0a0|>=3.8,<3.9.0a0|>=3.9,<3.10.0a0|>=3|>=3.6|>=2.7,<2.8.0a0|3.7.9|3.6.9|3.6.9|3.6.9|3.6.9|>=3.5.3',build='2_73_pypy|5_73_pypy|1_73_pypy|0_73_pypy|5_73_pypy|4_73_pypy|3_73_pypy|1_73_pypy|0_73_pypy']

Your python: python=3.7.10

I don't know how to interpret the above output, so I don't know what I need to do to get past this issue.

In case it matters, this is on an AWS EC2 instance with ARM/aarch64 architecture. Other common conda packages install without a problem.
