Version 2021.4 not installing

Great, thanks for the details, @simonhb!

My guess is that this is the problem - this version of glibc is over 10 years old. I set up a docker environment to test this hypothesis out in (the container version I am running here has glibc 2.13 installed in it):

docker run -it continuumio/miniconda3:3.9.0 /bin/bash \
  -c "conda update conda -y -q \
  && conda info \
  && conda install wget -y -q \
  && wget https://data.qiime2.org/distro/core/qiime2-2021.4-py38-linux-conda.yml \
  && conda env create -n qiime2-2021.4 --file qiime2-2021.4-py38-linux-conda.yml"

This fails with the following error:

ResolvePackageNotFound:

  - __glibc >=2.17,<3.0.a0

Is there any chance you can chat with your sysadmin to see about getting a version of glibc that is a bit more modern? It looks like 2.17 should get the job done.
