I had the same CRITICAL ERROR, for me worked
wget http://huttenhower.sph.harvard.edu/humann_data/chocophlan/full_chocophlan.v201901_v31.tar.gz --no-check-certificate
I have the same problem:
CRITICAL ERROR: Unable to download and extract from URL: https://huttenhower.sph.harvard.edu/humann_data4/chocophlan/full_chocophlan_SGB_202312.tar.gz
I have tried using wget, curl and via human_databases. I have also tried downloading different versions of the database and nothing works.
Where are you finding that 202312
URL? That’s not a database release I’m familiar with.
