suspect this is version 1.1 of libssl - try installing libssl1.0.2 - worked for me on a debian:9 install

[nopara73]

On Ubuntu 18.04 @ianmorty's suggestion worked by installing the following package: sudo apt-get install libssl1.0-dev

Public service for anyone in e.g. 2020 who finds this and discovers it's hard to get libssl1.0 any more, head here and scroll down to the "Still facing this in 2020?" part of the thread. Got me running. rvm/rvm#4764
