Sorry to bother you. I solved this by following https://github.com/rbenv/ruby-build/wiki#openssl-usrincludeopensslasn1_mach102-error-error-this-file-is-obsolete-please-update-your-software

I tried that 3 times and on the fourth time I just followed the ubuntu.

I managed to fix the issue with: sudo apt-get install -y zlib1g-dev

thanks for the response but I fixed this by following https://github.com/rbenv/ruby-build/wiki#openssl-usrincludeopensslasn1_mach102-error-error-this-file-is-obsolete-please-update-your-software or downgrading ssl. thanks

I got this too because I try to install ruby 2.3 which is not ok with openssl 1.1

It works for all ruby version greater than 2.4 👍🏼
