Conda install fails with: The environment is inconsistent, please check the package plan carefully #308

This is pretty much a new conda install and this start happening after a few reinstalls of the kernel

See https://github.com/elyra-ai/elyra/pull/767

conda install -y xeus-python -c conda-forge

This looks like a conda bug.

The conda solver is not super stable in my experience. In general, I recommend not using the full anaconda distribution or using the default channel, which tends to help with this. Also using mamba instead of conda shows more stability.

I was just trying to install using the recommended command from the project readme.md

conda install xeus-python notebook -c conda-forge

What is the recommended way to perform repetable installs on an environment that is not exclusive to xeus?

That seems about right. I don't know the specific bug that you are seeing but my experience with using the full anaconda distrib and then packages from conda-forge (or mixing channels in general) is not great, and not specifically with xeus. That is why we recommend using miniconda or miniforge.
