Hey @alexkrohn,
Sorry you're running into this, Ubuntu is certainly supported, and a common platform for us. I expect there's something misbehaving between what your processor supports, and what math library is being used (such as openBLAS or MKL, which numpy uses).
I guess to get started, could you tell us more about your processor? Ideally we would like to see the info in /proc/cpuinfo, so if you could run this command and upload the result, that would help out:
cat /proc/cpuinfo > cpuinfo.txt
Next could you provide the result of (in your environment):
conda list blas
and
conda list mkl
(I expect this one to be empty).
Last step, could you run this small script which will load each QIIME 2 plugin and print each import involved? Then if you could upload the result, I expect the last line to be our culprit:
python qiime_more_info.py > more_info.txt # remember to download the script
