QIIME2 installation problem

Hello everyone!
I use ubuntu 23.10 and I tried to install QIIME2 Amplicon Distribution using Conda.
I followed the installation guide and after 'conda env create -n qiime2-amplicon-2024.2 --file qiime2-amplicon-2024.2-py38-linux-conda.yml' I got an error:

Is this Conda or QIIME2 problem?

Hi @adriansh,

Welcome to the :qiime2: forum!

This looks like a conda problem...
I was able to find this post on stack overflow regarding this strict repo priority erorr which suggests that your conda configurations are causing the problem.

Can you run conda config --show and post the full output here.

Okay great!

Please run conda config --set channel_priority flexible then re run your environment command and it should work this time. If not I will be here to help :slight_smile:
