This question is similar to this and this but those aren't really helpful. I am trying to install the Ruby libraries and packages that Canvas needs. need to add a PPA in order to get the required Ruby version, by using the following commands:
sudo apt-get install software-properties-common
sudo add-apt-repository ppa:brightbox/ruby-ng
sudo apt-get update
Upon adding repository, I am getting this error:
PPA publishes dbgsym, you may need to include 'main/debug' component
Repository: 'deb https://ppa.launchpadcontent.net/brightbox/ruby-ng/ubuntu/ jammy main'
Description:

So if I try to install ruby 2.7 without running above commands, it will give an error which is obvious enter image description here I couldn't find any workaround as official documentation says the same.
I am using:
Distributor ID: Ubuntu
Description: Ubuntu 22.04.1 LTS
Release: 22.04
Codename: jammy
