bug#27858: Conda (on guix) does not activate environments

[Frederick Muriithi]

I have come across a bug on conda, installed via guix, that does not
seem to be present when conda is installed via the process at
https://conda.io/docs/install/quick.html#linux-miniconda-install

The issue
---------
Conda (on guix) does not activate environments

Command ran
-----------
source activate test-env

Expected result
---------------
The envinment should be activated, and the prompt changes from
`frederick@localhost:/tmp$` to `(test-guix-conda)
frederick@localhost:/tmp$`

Actual result
-------------
The terminal window is exited.

Additional information
----------------------
This behaviour is not present on conda installed via the process
presented in the conda documentation.

The environment(s) created by conda on guix are available on, and can
be activated by conda installed via the process in the conda
documentation.

I ran `bash -c "source activate test-env"` and the following error
message was displayed:

/gnu/store/f2dr9xbimg93pljm7xgmqb4cm5bxy98r-conda-4.3.16/bin/.deactivate-real:
line 59: return: can only `return' from a function or sourced script
/gnu/store/f2dr9xbimg93pljm7xgmqb4cm5bxy98r-conda-4.3.16/bin/.deactivate-real:
line 94: return: can only `return' from a function or sourced script

I would appreciate any help that would help in resolving this issue.

Hi Fred,

Can you send the exact commands you are using so we can replicate the
issue?

Pj.

1) Install conda into a profile:

    guix package --install=conda --profile=$HOME/guix_profiles/conda

2) Activate the profile:

    source $HOME/guix_profiles/conda/etc/profile

3) Create an environment with conda and install biopython

    conda create --name test-env biopython

4) Try to activate the environment (here's where it fails)

    source activate test-env

Additional Information

When installed from conda's documentation, conda installs the
following packages into conda's root environment by default:

asn1crypto, cffi, conda, conda-env, cryptography, idna, libffi,
openssl, packaging, pip, pycosat, pycparser, pyopenssl, pyparsing,
python, readline, requests, ruamel_yaml, setuptools, six, sqlite, tk,
wheel, xz, yaml, zlib


These do not exists in the root environment of the conda installed via guix.

I had never used conda before, so I was a bit surprised that it sneeked
that into my ~/.bashrc:

diff --git a/bash/.bashrc b/bash/.bashrc
index d0635bc..169b2c8 100644

+    fi
+fi
+unset __conda_setup
+# <<< conda initialize <<<
+

and required the presence of the 'sudo' command to be happy.

With that said,

$ guix environment --pure --ad-hoc conda bash coreutils sudo

(base) $ conda create --name test-env biopython

Then the suggested:

(base) $ conda activate test-env

(test-env) $

So, it seems to work.

Closing.
