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.
