Conda update conda - unexpected error (Win7)

[LilithElina]

Hi, I am trying to update conda on my Windows 7 laptop at work. Here is what happens:

C:\Anaconda>conda update conda Fetching package metadata: C:\Anaconda\lib\site-packages\requests\packages\urlli b3\util\ssl.py:315: SNIMissingWarning: An HTTPS request has been made, but the SNI (Subject Name Indication) extension to TLS is not available on this platform .

I also get the following traceback:

Here's my conda info:

C:\Anaconda>conda info Current conda install:

         platform : win-64
    conda version : 4.0.5

conda-build version : 1.3.1 python version : 2.7.6.final.0 requests version : 2.9.1 root environment : C:\Anaconda (writable) default environment : C:\Anaconda envs directories : C:\Anaconda\envs package cache : C:\Anaconda\pkgs channel URLs : https://repo.continuum.io/pkgs/free/win-64/ https://repo.continuum.io/pkgs/free/noarch/ https://repo.continuum.io/pkgs/pro/win-64/ https://repo.continuum.io/pkgs/pro/noarch/ config file : C:\Users\spo12.condarc is foreign system : False

What can I do to avoid that?

Thanks for your info, an easy fix will be remove the anaconda folder , and use the new miniconda installer to install latest conda (version 4.1.11). Or you can try use conda install to install conda 4.2,

command is following

 conda install -c conda-canary conda=4.2.1

Your version is 4.0.5 and I am not quite familiar with that version, and it may take some time to get the solution.

The command you posted gives the same error as the other things I've tried, so I guess I'm up for a new install.

Just one more question: what I actually wanted to do was get Junyper to work with an R kernel, but apparently junyper, as a command, is not working for me. I guessed my conda/Anaconda install was too old, because when I start ipython notebook it does say Junyper right on top of the page. Now that updating doesn't work, would it make sense to simply make a clean, new install of the whole Anaconda package?

I think reinstall Anaconda will be a easy fix. Uninstall and install anaconda are all relative easy.

We will make conda more and more stable

I will close this issue, and if you still have problems, feel free to reopen this and @ me
