tried adding trusted host and the trusted host command but nothing seems to work for me on centos 7.9
also tried adding trusted host in pip.ini file
tried with python 3.10 as well

How to Reproduce

Code of Conduct

I agree to follow the PSF Code of Conduct .

This isn't a pip issue. Your installation of Python is not built with the ssl module.
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.

If you run python3.10 -c "import ssl" , it will fail with something like

# ./python -c 'import ssl'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/root/Python-3.10.2/Lib/ssl.py", line 98, in <module>
    import _ssl             # if we can't import it, let the error propagate
ModuleNotFoundError: No module named '_ssl'
When compiling python, it said
Could not build the ssl module!
Python requires a OpenSSL 1.1.1 or newer
Python 3.10 requires at laeast OpenSSL 1.1.1 and the package installed by openssl-dev on CentOS 7 is version 1.0.2. You'll need to install a newer OpenSSL version and build Python against i.

I am using python 3.8 and if I try run python3.8 -c "import ssl" just works fine. What else could be this problem?

Also having the same issue on Ubuntu 18.04 with Python 3.8.10, still looking for a solution.
          Had this same problem, after updating my system (Manjaro linux). Before that I had no such issue.

I already had openssl 3.0.7 butI had to also install the openssl-1.1 package to get it working again

Thanks! That solved the issue for me. Also running Manjaro.
