User-defined Setup fails with existing Miniconda/Anaconda installation

[forman]

Expected behavior

When Cate's setup dialog pops up during first time installation or during updates users can choose between Automatic setup or User-defined setup. The latter has the option Install in new environment of existing Miniconda/Anaconda installation. It should install Cate as a new Python environment cate-env.

Actual behavior

If User-defined setup / Install in new environment of existing Miniconda/Anaconda installation is used, Cate tries to invoke the Conda activate script in the cate-env environment, which does not exist.

Specifications

Cate 2.0-dev16

I cannot reproduce the circumstances that would cause this problem to appear. Pausing this.

Ok, it turned out that during setup, the command

conda env create --name cate-env python=3

fails with error

SpecNotFound: Invalid name, try the format: user/package

The fix is not to use the conda env command but instead just

conda create --name cate-env python=3
