Error with glibc installing tetrad

[alexkrohn]

I am trying to install tetrad on a system running Ubuntu 20.04. I have ipyrad version 0.9.50 installed.

When I run conda install tetrad -c eaton-lab within the ipyrad environment (running python 3.7) I get the following error:

 Collecting package metadata (current_repodata.json): done

Your installed version is: 2.31

I take this to mean that I need glibc version 2.31 for tetrad, but that is the version I already have installed. sudo apt-get install libc6 reveals that I already have the latest version installed for 20.04.

Is this a problem with running tetrad on Ubuntu 20.04? Or am I missing something here?

Darn. conda install tetrad -c conda-forge works. Looks like the eaton-lab channel was not updated or something.
