I cannot successfully create the conda environment the following command `conda env create -n gatk -f gatkcondaenv.yml`, and have no idea how to fix it. Is there any solution to this problem?

Thank you very much

a) GATK version used

The Genome Analysis Toolkit (GATK) v4.1.4.1
HTSJDK Version: 2.21.0
Picard Version: 2.21.2

b) Exact GATK commands used

conda env create -n gatk -f gatkcondaenv.yml

c) The entire error log if applicable.

conda env create -n gatk -f gatkcondaenv.yml
