creation of conda environment fails on Ubuntu 18.04.5 LTS

I am trying to create a new environment for DSS. This is the console output:

I don't know. I have never tried this. It seems there are some version conflicts? I don't know what I can do to solve the problem. Sorry.

[ViHammer]

Oh, I thought you were maintaining the DSS packages. If that is not the case, you can close this issue. Do you know who might be responsible for the conda distribution of DSS?

[haowulab]

I am the maintainer, but i never used conda. I just make sure it works fine with bioconductor.
