17:34 <MatthewRapati[m]> hi, I have a question about installing an old version of jruby, I hope this is okay for this place, I am trying to install 9.1.17.0 on Ubuntu 20, and I get the error "Could not find a valid gem 'jruby-launcher' (>= 0) in any repository". I was able to get 9.3.0.0 to install on the same system without this issue. Any ideas? Thanks!
