Nextflow review @bobturneruk ep9, fastp conda error, libmamba

[ggrimes]

When I first tried the Conda exercise I got this error:

Error executing process > 'FASTP (1)'

Caused by:
  Failed to create Conda environment
  command: conda create --mkdir --yes --quiet --prefix /home/bobturner/nf-training/work/conda/env-a7a3a0d820eb46bc41ebf4f72d955e5f bioconda::fastp=0.12.4-0
  status : 1
  message:
    CondaValueError: You have chosen a non-default solver backend (libmamba) but it was not recognized. Choose one of: classic

I guess down to my Conda config. I could fix by:

conda config --set solver classic
