RE: PIP sudden ssl error - Larz60+ - Dec-18-2018

what package?

RE: PIP sudden ssl error - snippsat - Dec-18-2018

Try:

python -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip

Bug report, bug.

Quote:It appears the issue is a corporate proxy/firewall/mitm-box is not allowing traffic to pypi.org and/or files.pythonhosted.org.

Check your TLS version.
If your TLS version is less than 1.2 you have to upgrade it,
since the PyPI repository is on a brownout period of deprecating early TLS.

python -c "import urllib.request, json; print(json.loads(urllib.request.urlopen('https://www.howsmyssl.com/a/check').read())['tls_version'])"

Output:
TLS 1.2

Lars60+ -- ALL Packages nothing works currently

snippsat:

I ran
python -m pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org --upgrade pip

got
Could not install packages due to an EnvironmentError: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by ResponseError('toomany 503 error responses',)

replied with tls 1.2.

I have been developing this way forever what changed?

RE: PIP sudden ssl error - Vinod - Jan-29-2020

I am getting the same error while installing packages using PIP or while creating PIP/Virtual enviornment.
I have verified with network/Security team and they do not see any blocks for host - (host='files.pythonhosted.org', port=443)

Error:

Everything was working till day before yesterday and now its stopped working. Is there any immediate resolution for this?

RE: PIP sudden ssl error - pmpinaki - May-19-2020

In fact I face same issue and realized that zscalar is blocking. Until then I was using simple

pip install <package name>

Now i changed the command by adding additional parameter as trusted host
I install Jupyter by using below command and it works:

pip install --trusted-host pypi.python.org --trusted-host files.pythonhosted.org --trusted-host pypi.org jupyter

Can you try in similar way.
