How to solve an error that appears in conda proxy configuration?

Question

I am trying to install Rdkit on ubuntu and I have problem with the conda configuration.

I have reinstalled anaconda3 and python3 versions on my desktop and installed it from the beginning.

When I run the command: conda create -c rdkit -n my-rdkit-env rdkit

The error I am experiencing is this one:

Collecting package metadata (current_repodata.json): failed

ProxyError: Conda cannot proceed due to an error in your proxy configuration.
Check for typos and other configuration errors in any '.netrc' file in your home directory,
any environment variables ending in '_PROXY', and any other system-wide proxy
configuration settings.

Does anybody knows how to solve this problem, so that I can install the program called Rdkit?

Do you have a `.condarc` in your home directory that contain any proxy settings? Have you set `HTTP_PROXY` and or `HTTPS_PROXY`? Do you even need a proxy server set? — FlyingTeller, Nov 12 '19 at 13:22

I had this same error message when creating a new environment in Anaconda prompt using the command

conda create -n envname

Please see this answer in another similar question. It solved the problem for me: https://stackoverflow.com/a/68724703/9455395

Open your .condarc file and type the proxy servers as follows:

proxy_servers:
   http: proxyserver.org:portNumber
   https: proxyserver.org:portNumber

Make sure that the inputs do not include "http://" or "https://". Simply use the same server address in both.

The other user also made the note to add anaconda.org as well as anaconda.com to proxy server exceptions. I did not need to carry out this step.

To find your proxy, on Windows 10, try `Settings -> Network & Internet -> Proxy -> Address + Port`, that for `proxyserver.org:portNumber` in this answer. — Vladislav Povorozniuc, Feb 28 '23 at 21:02

I had a similar error on my work machine. I'm on Windows 10.

For me, the fix was to add *.anaconda.org to my list of proxy exceptions under Control Panel > Internet Options > Connections > LAN Settings > Advanced

Hope this helps.

Hi I had the same error.

In my case was that in environment variables from my computer I had

     HTTP_PROXY = value... 
     HTTPS_PROXY

In my case I didnt need that and I just removed them and it worked.

The reason is that Conda cannot continue due to proxy configuration errors.

The solutions are as follows: Open "Internet Options" in the Internet -> Connection -> LAN Settings -> uncheck the "Use a proxy server for Lan".

This may work, but doesn't this reduce the security of your internet connection? – Piethon May 27 '23 at 00:55

I used the following settings in the .condarc and it worked:

channels:
- defaults

show_channel_urls: True
allow_other_channels: True

proxy_servers:
    http: 127.0.0.1:<Cntlm_Port_number>
    https: 127.0.0.1:<Cntlm_Port_number>

ssl_verify: True

Note: In my machine, our IT team had set a Proxy and if I turn off that proxy I cannot have access to the internet at all. With that said, I used the above config and now I can run conda create --name <env_name>

PS: By Cntlm I mean this.

I had the same issue today on Linux 18.04. I solved it by adding my username and password when exporting the $http_proxy and $https_proxy

Here is an command structure:

$ export http_proxy=http://username:password@proxy:port
$ export https_proxy=https://username:password@proxy:port

If your password contain special character such as !@#$%, make sure to input it as Flash code. For example #->%23, @->%40. You can search it for more symbol.

Also I have removed the .condarc file from the home directory.

Hope this work for you.

Hi I face the same issue now. Earlier it used to work. But now I get the above error. My proxies are stored in ~/.bash_profile and not on .condarc. I guess after updating system, it has stopped working — Baktaawar, Nov 16 '20 at 19:54

To run Conda on Linux without the error:

Collecting package metadata (current_repodata.json): done
Solving environment: done

ProxyError: Conda cannot proceed due to an error in your proxy configuration.
Check for typos and other configuration errors in any '.netrc' file in your home directory,
any environment variables ending in '_PROXY', and any other system-wide proxy
configuration settings.

Execute the following commands to unset these agents:

unset  https_proxy
unset  http_proxy
unset  no_proxy
unset  HTTPS_PROXY
unset  HTTP_PROXY
unset  NO_PROXY

I had the same error on my Windows 10.

I solved it by:

try to close the proxy software;
setting-> network and internet-> proxy-> take off "use a proxy server" . enter image description here

Or Open Control panel -> Internet Options -> Connection -> LAN Settings -> uncheck the "Use a proxy server for your Lan".
