Any ideas, how to fix this error?

You can try retrying as the error message says.

HTTP errors are often intermittent, and a simple retry will get you on your way.

Did you add this channel https://conda.binstar.org/chria manually to your conda environment? If so, can you try removing this channel by doing,

using Conda
Conda.rm_channel("https://conda.binstar.org/chria")

I tried your suggestion, but it doesn’t help:

julia> using Conda

julia> Conda.rm_channel("https://conda.binstar.org/chria")
CondaKeyError: 'channels': u'https://conda.binstar.org/chria' is not in the u'channels' key of the config file

Furthermore, this is an SSL error: "SSLError(SSLError(CertificateError(“hostname ‘conda.binstar.org’ doesn’t match either of ‘anaconda.com’, ‘anacondacloud.com’, ‘anacondacloud.org’, ‘binstar.org’, ‘wakari.io’”,),),)
"
It is not an error saying the web server would be unavailable. I thing this is a bug, but I don’t know where. Any idea? Could anybody else who is using Linux try to install this package and tell, if the installation works?

I tried:

Conda.update()

and it fails with the same error.

isuruf · July 9, 2017, 5:37pm

Can you post the output of the following?

using Conda
Conda.runconda(`info`)

ufechner7 · July 9, 2017, 5:58pm

Ok, I found a solution. I opened a terminal and removed all but the default channel from my local minicoda installation.
I used conda config --get channels to list my channels and used conda config --remove channels ‘X’ to remove channel X.
It is annoying that Julia packages depend on a different package manager, that was installed outside of Julia.

Thank you for your help anyway!
