install 2.3.1 in ubuntu 19.04

You can install previous versions of Ruby following this instructions posted on this RVM github issue: rvm/rvm#4680 (comment)

I did the same as @grhansen suggested. I was installing ruby 2.3 and that required libssl1.0-dev. I am using Ubuntu 19.04. So I opened my /etc/apt/sources.list by

sudo nano /etc/apt/sources.list.

And then add the following line at the end of the file

deb http://security.ubuntu.com/ubuntu bionic-security main.

After that I run the command

sudo apt update

from the terminal. Then I run the command

apt-cache policy libssl1.0-dev

from the terminal and I got the following output

libssl1.0-dev: Installed: (none) Candidate: 1.0.2n-1ubuntu5.3 Version table: 1.0.2n-1ubuntu5.3 500 500 http://security.ubuntu.com/ubuntu bionic-security/main amd64 Packages

Then I run the command

sudo apt-get install libssl1.0-dev

And it is installed then

Before adding I was getting

libssl1.0-dev: Installed: (none) Candidate: (none) Version table:
