Error in qiime 2021.08 Found conflicts! Looking for incompatible packages

Hello everyone!

I am trying to install the latest version of QIIME2 (qiime2-2021.08) on Ubuntu, but some conflicts appear:

conda env create -n qiime2-2021.8 --file qiime2-2021.8-py38-linux-conda.yml
Collecting package metadata (repodata.json): done
Solving environment: |
Found conflicts! Looking for incompatible packages.
This can take several minutes. Press CTRL-C to abort. \ failed

CondaError: KeyboardInterrupt

I realized that same error have happened on 2020.11, Instalation qiime 2020.11 Found conflicts! Looking for incompatible packages so I assume that this might be a problem with this yml file? Cause I've installed 2020.11 version again and it works just fine.

Does anybody have any suggestions?
Thank you very much in advance!

Hey there @zikaishao!

I just performed a clean linux-based install in a new virtual machine, all good here. Let's try to figure out what might be different between our two computational environments.

Can you run the following and share the results here - this'll help give us an idea about your system:

env
conda info -a

:qiime2:

Hi @thermokarst , thanks for your reply!

The results of env are:

Hi @zikaishao, thanks for the info!

Nothing immediately jumps out at me, except that it looks like you're using a few channel mirrors. Are you operating behind a national firewall? If so, we've seen problems related to that in the past, unfortunately I don't know if there is much we can do about that. Can you try one of our Docker images or Virtualbox VMs?
