The openssl version that python3.10+ needs should be greater than 1.1.1? Note PEP-644 which requires OpenSSL >= 1.1. 1 is released in Python 3.10

• The openssl version in my debian9 is 1.0.2o. Detail:

  ➜  which openssl
  /usr/local/bin/openssl
  ➜  openssl version
  OpenSSL 1.0.2o  27 Mar 2018
  

  but when I update openssl, It shows me that openssl is already the newest version (1.1.0l-1~deb9u6)

  ➜ sudo apt-get install openssl
  Reading package lists... Done
  Building dependency tree
  Reading state information... Done
  openssl is already the newest version (1.1.0l-1~deb9u6).
  0 upgraded, 0 newly installed, 0 to remove and 1 not upgraded.
  

So, I wonder how can I update openssl version greater than 1.1.1?
