Doing pythonz install 2.7.9 on Ubuntu 18 comes without ssl support:

If the python version you are trying to install is equal or lower than 2.7.12, it does not support OpenSSL1.1.0, so you would need to replace libssl-dev with libssl1.0-dev.

Ubuntu 18.04 is the first official release to switch to OpenSSL1.1.0 which is why you might not have been impacted with this in the past.

In homebrew in macOS we have --with-openssl option. For Ubuntu, do we have something similar for pythonz installation? Or am I stuck downloading the tar.gz of the old installation and messing up with https://superuser.com/a/1346305 or https://stackoverflow.com/a/5939170?

@idgserpro Hello, apt install libssl1.0-dev and then pythonz install 2.7.9 works for me.
