Hi there! I was facing the same problem and i fixed using the command:
\curl -sSL https://get.rvm.io | bash -s stable --ruby
This command allows you to install RVM stable with ruby, in case you want to know more options in your installation check the RVM install guide here. Maybe there is an issue with your operating system. Let me know if it worked for you!

@pankaj-dahiya-sp Thanks for reporting this issue. Sounds like you're facing a missing certificate from Canonical PPAs. Are you trying this under a docker container? If yes, try this solution:

sudo apt install ca-certificates

@cnebril2020 Yes, install rvm directly is always an option. The downside is that you'll miss automatic updates from rvm.
