conda update CondaHTTPError: HTTP None

Question

Midway through running Conda Update --all, the update stalled. Multiple packages had been updated. Now, when I run conda update --all or conda update conda, I get this response:

(C:\Users\*****\AppData\Local\Continuum\Anaconda3) C:\Users\*****>conda update conda
Fetching package metadata ...

CondaHTTPError: HTTP None None for url <None>

An HTTP error occurred when trying to retrieve this URL.
HTTP errors are often intermittent, and a simple retry will get you on your way.
SSLError(SSLError(SSLError("bad handshake: Error([('SSL routines', 'ssl3_get_server_certificate', 'certificate verify failed')],)",),),)

I've repeated conda update conda over multiple days, with no change in results. I can see there is no HTTP, however conda info --a shows channel URLs.

How do I get conda update to call a correct HTTP address?

I had the same error but in my case it was the the firewall in bitdefender antivirus software causing the trouble. I was using miniconda3 on Ubuntu 22.04 (Windows Subsystem for Linux) installed so somehow bitdefender didn't recognize that as a legitimate software. After making a rule to allow svchost.exe, everything went to normal. Leaving this comment for anyone who faces the same issue. — Sarthchoudhary, May 19 '22 at 06:49

My original answer got flagged as duplicate because I answered a similar question with the same answer, I wasn't aware that this is not allowed. I have marked my other response as a duplicate. Hopefully, this stays up!

I almost spent two days running in circles trying all the solutions I could find on the Internet, but here is what worked for me.

So, CondaHTTPError aka SSL module is not available error is caused by the missing/misplacement of libcrypto file in anaconda3/DLLs folder:

Tl;dr:

From anaconda3\Library\bin copy below files and paste them in anaconda3/DLLs:

-   libcrypto-1_1-x64.dll
-   libssl-1_1-x64.dll

Detailed answer:

Uninstall any Python versions you have (e.g. Python 3.7 or Python 3.8)

go to Control Panel--> Program and Features--> Select Python-->

uninstall

Uninstall any Anaconda versions you might have (e.g. Anaconda or miniConda) For Anaconda:

go to Control Panel--> Program and Features--> Select Anaconda-->uninstall

For miniConda

go to Control Panel--> Program and Features--> Select miniconda--> uninstall
Delete any leftover Environment variables

go to Control Panel--> System--> Advanced System settings (on left side)--> in System Properties click on Environment Variables button--> in User Variable select Path and click the Edit button--> delete any path related to Anaconda, miniConda or Python.
```
E.g.
C:\Users\Bob \AppData\Local\Programs\Anaconda\...
C:\Users\Bob \AppData\Local\Programs\miniconda\...
```
b. If you don’t see any paths related to Anaconda, miniConda or Python; you are good to go.
Reboot your machine
Download the latest version of Anaconda
Run the Installer; keep all the default settings
Go to your anaconda3/library/bin folder:

E.g.C:\Users\Bob\AppData\Local\Continuum\anaconda3\Library\bin
Copy these files:

libcrypto-1_1-x64.dll

libssl-1_1-x64.dll
paste these in anaconda3/DLLs folder:
Reopen the Anaconda Prompt and test with any command that requires an Internet connection. E.g. conda update conda Or with conda update --all

the TLDR did it for me when creating my first env after a fresh install of miniconda, thank you — mmurrietta, Sep 13 '20 at 04:53
In my case, I had to also move libssl-1_1-x64.dll and pdb from \anaconda3\Library\bin to \anaconda3\DLLs — Embid123, Jan 17 '21 at 11:12
This worked on a fresh install of anaconda and started from step 7. — Heymans, May 17 '21 at 05:40
Is this just an Anaconda bug? It's hard to believe since it's been 2 years. — user118967, Aug 24 '22 at 00:24

Check if you're behind a corporate firewall that has an HTTPS/SSL proxy. If so, you may need to change the line in .condarc from ssl_verify: true to ssl_verify: false.

Or, as suggested by th0masb in the comments, using the command:

conda config --set ssl_verify false

I faced the same problem on Mac OS X and with Miniconda. After trying many of the proposed solutions for hours I found that I needed to correctly set Condas environment to use the Root certificate that my company provided rather than the generic ones that Conda provides.

Here is how I solved it:

Open Chrome, got to any website, click on the lock icon on the left of the URL. Click on «Certificate» on the dropdown. In the next window you see a stack of certificates. The uppermost (aka top line in window) is the root certificate (e.g. Zscaler Root CA in my case, yours will very likely be a different one).
Open Mac OS keychain, click on «Certificates» and choose among the many certificates the root certificate that you just identified. Export this to any folder of your choosing.
Convert this certificate with openssl: openssl x509 -inform der -in /path/to/your/certificate.cer -out /path/to/converted/certificate.pem
For a quick check set your shell to acknowledge the certificate: export REQUESTS_CA_BUNDLE=/path/to/converted/certificate.pem
To set this permanently open your shell profile (.bshrs or e.g. .zshrc) and add this line: export REQUESTS_CA_BUNDLE=/path/to/converted/certificate.pem. Now exit your terminal/shell and reopen. Check again.

You should be set and Conda should work fine.

PS: I'm aware that OP works on Windows. Nonetheless I leave this solution here because I think it can help solving the underlying root cause.

You are my hero. This worked for me but I was able to export to pem and skip the openssl step. — user68311, Nov 06 '20 at 00:02
It also is the correct solution, conda relies on on `requests` and this environment variable _is_ the way to configure it. — serverhorror, Jun 09 '21 at 15:25

I am using python 3.7.4 and I have just downloaded the conda and tried setting up the tensorflow but got http error. I tried several steps mentioned above but it dint solve my problem. I solved it by first activating conda. if you are using conda for first time you need to activate it using conda init command and then disable SSL verification conda config --set ssl_verify false After above steps my tfp setup worked perfectly!!!

You should check your .condarc file located in your Miniconda3/Anaconda3 root directory. There should be a line with just a hyphen. This line corresponds to the None channel. Deleting the line fixed the issue for me.

For the type of error above, you have to remove the proxy in environment variable. To do this follow this step :-

Open the Environment Variables window==>>>>>

To make many of the edits shown in this article, you first need to open the Environment Variables window. This guide explains how to open this window and shows you the basics about working with environment variables: Simple questions: What are environment variables in Windows?

If you want to skip reading it, one path that works the same in all versions of Windows is to open the Control Panel and go to “System and Security - > System.” There, click or tap the “Advanced system settings” link on the left. The System Properties window is opened. There click the Environment Variables button.

In this you have to select that one which have proxy , and delete ,then click Ok. Now restart your Anaconda prompt. It worked for me; I hope it also work for you.
Good luck

Enable 'k' flag in your conda update command. For example,

conda update anaconda-navigator -k

That will allow conda to make insecure connections to download packages. This is especially useful when you are behind a proxy server.

The DLLs delivered by Anaconda3 are located here: D:\Anaconda3\Library\bin

My workaround: I have copied the following files

Just need to add binaries into you path, and done - it will take care about your openssl and everything.

Search environment variables, in both User and System variables. Add the bin location in Path. Put the path at the end without changing anything. Save Apply and re-open your terminal. It should be now allowing you to install libraries easily.

I had the same error, and I tried most of the methods, but none of them worked. I checked the version of anaconda3 it was 4.2.0 which I realized was in beta which might be the reason.

I solved it by uninstalling everything and installing the latest version (5.1.0). It worked after that.

I also faced the same problem and manually followed these steps to reach the desired result. you can enter --> https://repo.anaconda.com/pkgs/main/win-64/ you can install packeges whatever you want and later : you can write to Anaconda Prompt -->

conda install C:\Users\xxxx\Downloads\xlrd-1.2.0-py37_0.tar.bz2

Tried everything to fix this issue. Hours of wasted time.

Reset Windows 10 firewall
downgraded/upgraded pip
downgraded/upgraded conda
tried new environments
installed pip from pypi (get-pip.py)
upgraded Debian on Windows environment

Nothing fixed it. Then noticed that other conda environments worked perfectly. The issue was the pip cache was mangled if you reinstalled an environment with a name you used before and did some sort of upgrade of conda/distro in-between. Under linux i ran the following to fix the issue:

rm -rf $HOME/.cache

and looks like there is a similar setup for Windows based on the info you gave above.

As suggested by others this could happen when you've a firewall with SSL proxy on your system. A quick fix in this case would be to change the conda config to ignore SSL verification by:

conda config --set ssl_verify false

But doing this exposes you to potential vulnerabilities, hence it is recommended to run this after you've successfully performed the operation that was giving you CondaHTTPError earlier:

conda config --set ssl_verify true

This will re-enable SSL verification in conda
