It seems the issue is not with rbenv but with other version managers like chruby and asdf also. The real problem is compatibility issue with openssl and ruby 2.3.x.
The openssl extension of Ruby version before 2.4 is not compatible with OpenSSL 1.1.x. At the moment, most Linux distributions that come with OpenSSL 1.1.0 have a separate package for OpenSSL 1.0.x.
You need to install the earlier version of OpenSSL or use ruby 2.4.x.
sudo apt-get install autoconf bison build-essential libyaml-dev libreadline6-dev zlib1g-dev libncurses5-dev libffi-dev libgdbm5 libgdbm-dev libdb-dev
sudo apt-get install libssl1.0-dev
This solved my issue.
libgdbm5 for Ubuntu19 or Mint19 and libgdbm6 for later versions.
for MacOS and Home brew see https://github.com/rbenv/ruby-build/wiki#openssl-version-compatibility
