Issue

What were you trying to do that didn't work? pip3.9 does not reliably work through a proxy when defind via $https_proxy environment variable. Please provide the package NVR for which bug is seen: python3-pip-21.2.3-7.el9.noarch How reproducible: Every time Steps to reproduce 1.  Set up a proxy. It can be a simple Squid proxy on any RHEL version (tested with RHEL 7). 2. # export https_proxy=https://<proxy_hostname>:8080 3. # pip3.9 install pymssql Expected results The pymssql package is downloaded and installed. Actual results The following gets printed to the console: [root@r93 ~]# pip3.9 install pymssql WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1129)'))': /simple/pymssql/ WARNING: Retrying (Retry(total=3, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1129)'))': /simple/pymssql/ WARNING: Retrying (Retry(total=2, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1129)'))': /simple/pymssql/ WARNING: Retrying (Retry(total=1, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1129)'))': /simple/pymssql/ WARNING: Retrying (Retry(total=0, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1129)'))': /simple/pymssql/ Could not fetch URL [https://pypi.org/simple/pymssql/:] There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pymssql/ (Caused by SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1129)'))) - skipping ERROR: Could not find a version that satisfies the requirement pymssql (from versions: none) ERROR: No matching distribution found for pymssql Could not fetch URL [https://pypi.org/simple/pip/:] There was a problem confirming the ssl certificate: HTTPSConnectionPool(host='pypi.org', port=443): Max retries exceeded with url: /simple/pip/ (Caused by SSLError(SSLError(1, '[SSL: WRONG_VERSION_NUMBER] wrong version number (_ssl.c:1129)'))) - skipping [root@r93 ~]# Note that RHEL 8 is unaffected by this. Additionally, a workaround exists for RHEL 9 whereby if the proxy is defined as follows, the issue is not triggered: # export https_proxy=http://<proxy_hostname>:8080 Possibly related to https://github.com/pypa/pip/issues/9568. Applied the fix in https://github.com/pypa/pip/pull/10680 but it does not seem to work.
