Update the conda version in the base image

[ocefpaf]

I am trying to build a binder using the this env file which is quite sensitive to the channel order. Binder builds just fine but I get the wrong version some of its dependencies (icu), and a broken env :unamused:

When using the same env file locally I get the right versions, so I am guessing the issue is the conda version used in binder.

I am trying now to use the Dockerfile approach, and update conda before creating the env. See https://github.com/ocefpaf/notebooks_demos/blob/master/Dockerfile#L8 but that is returning:

# > source deactivate IOOS #
---> 70edd36d67f6
Removing intermediate container 941826cb2cef
Step 15 : RUN source activate IOOS
---> Running in e2274012c0a4
/bin/sh: 1: source: not found
could not build image ocefpaf-notebooks_demos: Error: build failed for imageName: ocefpaf-notebooks_demos
registering template for ocefpaf-notebooks_demos

See http://mybinder.org/status/ocefpaf/notebooks_demos

Any recommendations? Is a conda update possible? (So the channel preference feature is enabled.)

Can we take advantage of the channel preference feature? Or would that break binder dependencies?

Hi, I have exactly the same issue (with the gdal package on conda-forge).

My understanding is that binder always downloads the latest miniconda, which should do the job.

I guess that redeploying would do the trick.

BTW adding this line fixed it for me. So I am closing this.

Well, this forces me to use docker instead of a pure conda....
