Can't conda install or update packages - maybe not reaching our proxy server

Hey, we've been trying for months to conda install packages and conda update --all, but we do not seem to be reaching our organization's proxy server.

We've re-installed the individual version of Anaconda (versions Anaconda3-2020.11-Windows-x86_64, and Anaconda3-2021.05-Windows-x86_64) on two different pieces of hardware (one i5, the other i7), as individual user (not system), without adding a PATH. We are running 64-bit Windows 10 Enterprise V1909.

After opening Anaconda, click Environment -> Base -> Terminal

... and on first attempt (out of the box, all defaults), we get the following error:

----------------------------> error below

(base) C:\Users\Dyer01>conda update --all

Collecting package metadata (current_repodata.json): failed

CondaHTTPError: HTTP 000 CONNECTION FAILED for url <https://repo.anaconda.com/pkgs/main/win-64/current_repodata.json>

Elapsed: -

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.

If your current network has https://www.anaconda.com blocked, please file

a support request with your network engineering team.

'https://repo.anaconda.com/pkgs/main/win-64'

<-------------- error above

No number of retries gets us on our way. The network definitely is not blocking anaconda.com, and the network engineering team have tried their hardest to find a solution.

If we add the HTTP_PROXY= details to the system settings, and change ssl_verify=false in the .condarc file, the only other error we get is:

---------> error below

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.

<------------------- error above

Our proxy manager assures us that there is no indication of a request being made to/via the proxy server. We cannot find any .netrc files (some netrc.pyx files); and checked all known system-wide proxy configuration settings.

If we set the proxy with the Anaconda Terminal, with "set HTTPS_PROXY=https://proxy_userid:proxy_password@proxy_ip:proxy_port" we get the following detailed error report (which also cannot be sent):

--------------------> error below

An unexpected error has occurred. Conda has prepared the above report.

Would you like conda to send this report to the core maintainers?

<---------------------- error above

We figure it is a small issue somewhere in the configuration, but are at a loss what else we can try; or what we can do to isolate the problem. We'd greatly appreciate some ideas to either diagnose or address the potential problem.

In my case, I added one new file and modified one old file. The modified file ~/.condarc contains

proxy_servers:

http: http://user:pass...@proxy.com:port

https: http://user:pass...@proxy.com:port

.

---

Here one must remember that symbols like @, #, $, % must be replaced by %40 (@),%23 (#),%24($) ,%25 etc. I stopped system-wide proxy declaration and preferred to use corresponding conf file. This will help to update using conda while it is not useful for pip.

For pip, I created a new file ~/.config/pip/pip.conf where I entered

[global]

proxy = http://user:pass...@proxy.com:port

Trust this may help to resolve the issue.

Thanks for your suggestion. While this wasnt the solution, I followed another suggestion for the proxy_servers entry (no prefixes) from Github, in .condarc:

channels:
- defaults
ssl_verify: false --------OR-------- true
show_channel_urls: true
allow_other_channels: true
proxy_servers: {http: user:pa...@corp.com:8080, https: user:pa...@corp.com:8080}

now in the terminal, there is NO error, but it also does not look as if the update really happens - I thought there should log details of what is updated(?). This is what the terminal output looks like:

(base) C:\Users\Dyer01>conda update --all

[y/N]: y

(base) C:\Users\Dyer01>conda install -c conda-forge dowhy
[y/N]: y

(base) C:\Users\Dyer01>conda install -c conda-forge python-docx
[y/N]: y

BUT, it does not seem to run through the update, and if I "import dowhy" in python, it says there is no module dowhy.
