installing Ruby Version Manager

Personal experience
  • Works in Kubuntu 18.04.
  • Tested in Kubuntu 17.10.

Use sudo apt-add-repository -y ppa:rael-gc/rvm && sudo apt-get update && sudo apt-get install rvm -y to install from Ubuntu PPA. Open Gnome Terminal with gnome-terminal, then use Edit > Preferences > Command and enable Run command as a login shell. Reboot. Verify installation with rvm -v.

If necessary, open Gnome Terminal with gnome-terminal, then use rvm install ruby to install Ruby. Determine which Ruby version is available with rvm list, for example ruby-2.6.0, then use rvm alias create default foobar && rvm use foobar to specify the Ruby version used by Ruby Version Manager, where foobar represents a Ruby version, for example ruby-2.6.0.
