adding eupsforge.net/conda/dev as a channel raises an error

[danielsf]

Just running conda config --add channels http://eupsforge.net/conda/dev gives

Error: Could not parse the yaml file. Use -f to use the yaml parser (this will remove any structure or comments from the existing .condarc file). Reason: couldn't parse modified yaml

This can be avoided with conda config --force --add channels http://eupsforge.net/conda/dev, but the behavior seems odd.

Did you have a hand-modified ~/.condarc? I've seen similar errors when I'd modify it by hand and introduce mistakes.

Could you check if this is reproducible?

[danielsf]

I have never touched my .condarc

I have already experienced this problem both on my laptop and on lsst-dev. Is there another test you would like me to perform?

[mjuric]

Can you give me steps to reproduce it? I'm failing miserably right now :(.

[danielsf]

it really is just

conda config --add channels http://eupsforge.net/conda/dev

my PATH is

/home/danielsf/conda-lsst/bin/:/home/danielsf/conda-lsst/miniconda/bin/:/opt/rh/devtoolset-3/root/usr/bin:/usr/lib64/qt-3.3/bin:/usr/local/bin:/bin:/usr/bin:/usr/local/sbin:/usr/sbin:/sbin:/home/danielsf/bin

which conda is

~/conda-lsst/miniconda/bin/conda

and my .condarc is

channels:

• http://eupsforge.net/conda/dev_testing
• defaults

For what it's worth, if I first remove the dev channel and then try to add it again, I also get the error.

[ewok:~/lsstRepos/conda-lsst/miniconda] lynnej% conda config --remove channels http://eupsforge.net/conda/dev --force [ewok:~/lsstRepos/conda-lsst/miniconda] lynnej% more ~/.condarc channels:

• defaults [ewok:~/lsstRepos/conda-lsst/miniconda] lynnej% conda config --add channels http://eupsforge.net/conda/dev Error: Could not parse the yaml file. Use -f to use the yaml parser (this will remove any structure or comments from the existing .condarc file). Reason: couldn't parse modified yaml [ewok:~/lsstRepos/conda-lsst/miniconda] lynnej%

However, if I then completely remove the ~/.condarc file and try to add it the channel, it works. [ewok:~/lsstRepos/conda-lsst/miniconda] lynnej% rm ~/.condarc remove /Users/lynnej/.condarc? y [ewok:~/lsstRepos/conda-lsst/miniconda] lynnej% conda config --add channels http://eupsforge.net/conda/dev [ewok:~/lsstRepos/conda-lsst/miniconda] lynnej%

True: I also did not start seeing this error until I tried removing a channel with conda config --remove

[rhiannonlynne]

I think the 'remove' feature must be buggy. The fact that you have to use --force in order to use it might be an indication.

This is beginning to sound familiar -- I think @cwwalter encountered this as well (and we traced it to a bug in conda config --remove, and then I forgot about it). I'll open an issue with upstream.

[cwwalter]

Yes, that's correct. I had to manually remove the file.

Issue opened upstream: https://github.com/conda/conda/issues/2013

In the meantime, don't use conda --remove to manipulate ~/.condarc; edit it by hand, if needed.
