If you are running ./configure on a new download of Python and you get this:
checking whether compiling and linking against OpenSSL works... no
And you already have openssl installed...
Make test after a build returns:
Could not build the ssl module! Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host(). LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381
just do:
sudo apt-get install libssl-dev
Now when you run ./configure you should see:
checking whether compiling and linking against OpenSSL works... yes checking for X509_VERIFY_PARAM_set1_host in libssl... yes checking for --with-ssl-default-suites... python
