Update/Install in conda failing with the error: An HTTP error occurred when trying to retrieve this URL #9504

I am using my corporate admin account on Windows 7. And I have also disabled ssl_verfy.

connectys · 2018-06-14T14:45:57Z

Hi Jeorme,

Solution is to make changes in .condarc file. You would need to add proxy servers in the file to get rid of these errors.

ashukrishna100 · 2018-09-26T15:27:54Z

I recently got this issue resolved. Use this command to see proxy_servers
conda config --show

If any proxy server is present in the configuration. Kindly use
conda config --remove-key proxy_servers. It will remove saved proxy servers from anaconda configuration.
Enter
conda clean --source-cache
Now your http error is gone.
Give it a try and let me know in case of any difficulty.

johnrogers1939 · 2018-09-27T09:15:33Z

Followed ashkrishna100 above, set ssl_verify false, turned off firewall & still got SSLError bad handshake!

ashukrishna100 · 2018-09-27T13:21:10Z

Get a fresh copy of condarc file. Don't set SSL verify as of now. Then give it a try.
Remove environmental variables and also open credentials manager. Clear any saved passwords over there.

johnrogers1939 · 2018-09-28T06:51:59Z

Hi Thanks for the email. Unfortunately, as a newcomer to conda, I am not sure I have done what you suggest properly – my attempts to update still fail. condarc file: channels: - defaults ssl_verify: false report error: true envs_dirs: SSL verify: set to “false”. I am attaching the output of “conda config –show” & “conda update conda”. Thanks in anticipation of you help.

ashukrishna100 · 2018-09-28T13:51:42Z

Hi John,
Bad handshake error is when u set SSL verify to false. Not only for conda ,but if you write simple python code with set SSL_verify to False. It would throw bad handshake error in most of the cases where we are using HTTPS protocol. I would suggest you to remove set SSL_verify from the condarc. Download the fresh default condarc file. As per the current version of condarc,they don't set the SSL to false.
Repeat the above said steps then. U might get away with the error.
Note- get fresh condarc file from any of your colleagues who has a working conda. It would be in pkgs/conda4.5.4/info/test folder.

Also if there are corporate firewalls,please set the proxy in the prompt by using
set http_proxy=http://username: password@domain.com:{port}
set https_proxy=https://username: password@domain.com:{port}

sorenwacker · 2019-01-20T18:17:21Z

Why would it stop working from one second to another?

jonreade · 2019-03-31T18:41:07Z

I've had exactly the same. One minute it was working, literally the next it stopped. No corporate firewalls involved, internet connection fast, stable and up and running with no blips. Really do wonder if the bother of an extra layer is worth it when you get this kind of grief.

AriaGu · 2019-04-16T02:13:40Z

Why would it stop working from one second to another?

you should enter the command in the anaconda prompt instead of in cmd

msarahan · 2019-04-16T02:47:14Z

It is because of library loading. Behavior changed in recent python builds. See https://conda.io/projects/conda/en/latest/user-guide/troubleshooting.html#condahttperror-http-000-connection-failed for more details and ideas on workarounds. We are working to improve conda, too, so that workarounds are not necessary. The way that Windows does shared library finding is pretty annoying, but we're working to make it better.

Jaguar100 · 2019-05-01T14:18:28Z

Hi. I'm also getting "### CondaHTTPError: HTTP 000 CONNECTION FAILED for url https://repo.anaconda.com/pkgs/r/noarch/repodata.json.bz2". Nothing Works

I cannot install packages or update conda or any existing packages. I've tried the following from this and other posts - though some I am unable to do because I don't know how (indicated below). I am an analytics guy so not super familiar with Command line code. No luck with anything. I am on a corporate network with a firewall and using the Navigator Prompt. Can someone please help me! Does it come down to me needing a proxy server or path of a certificate bundle from my network admin? Thanks ahead of time!

OpenSSL: No luck. I don't have the required Admin rights to install this app.
Proxy Server and Cache Cleaning approach @MuqadderIqbal: No luck.
Adding environment paths: have not tried this as I don't know how to change the paths
conda config --set ssl_verify no (& "false): Neither worked
Update the condarc file: I don't know how to do this. So could not due the following as someone recommend:
channels:
defaults
ssl_verify: true
proxy_servers:
http: http://proxy_server:port
https: https://proxy_server:port
Activate Environments: I do not understand how to do this.
pip install --trusted-host pypi.org: ERROR: You must give at least one requirement to install (see "pip help install")
@msarahan - I tried the workarounds in your link above but none of them seemed to work (())

csoja · 2019-05-03T14:17:18Z

@Jaguar100 As you are on a corporate network with a firewall, it is likely you will need to add your proxy server to your .condarc file.
See the conda documentation: https://conda.io/projects/conda/en/latest/user-guide/configuration/use-condarc.html#configure-conda-for-use-behind-a-proxy-server-proxy-servers
Assuming you are on Windows, you should open the Anaconda Prompt and type "conda info". This will tell you where you .condarc file is located among other things. It is a text file, so you can edit it however you edit other text files.

Jaguar100 · 2019-05-05T16:03:18Z

Thanks @csoja. How does one access, open and tweak/change the ".condarc" file?

I had this same issue

Help!!!

ycbelgium · 2021-07-11T18:34:45Z

your SSL module is not available.
Download open SSL (Win64 OpenSSL v1.1.1d) here: Link
Then it should work
make sure you have installed Microsoft Visual C++ installed

Questdream · 2021-08-23T09:43:12Z

Change "HTTPS" to "HTTP" in. Condarc.
It works for me.

irgot · 2021-11-25T00:52:21Z

Try to run "conda activate base" first, then it will probably ask you to initializa env.

Zeweiwang0 · 2021-12-01T13:55:36Z

I had this same issue

conda config --set ssl_verify False

solved it for me.

I'm running Conda 4.8.2 on Windows 10 in 'corporate' style environment.

It really works for me thanks

Ankitapal1995 · 2022-08-04T07:11:19Z

I had solved this issue by adding proxy_server in .condarc file.
first open linux terminal, type echo "$http_proxy" to find the proxy, copy it
then open .condarc file and add these following line and paste your proxy
proxy_servers: http: http://*****************:8080 https: http://****************:8080
I hope it will solve your issue. To know about it better follow this link
https://docs.anaconda.com/anaconda/user-guide/tasks/proxy/
