Please can someone help me to install ruby 3.0 on Ubuntu I can’t install it, rbenv don’t show me this version I have update all my Ubuntu

it sounds like you’ll need to update ruby-build to get all the latest versions of ruby through rbenv. https://makandracards.com/makandra/25477-rbenv-how-to-update-list-of-available-ruby-versions-on-linux

When I do the command to update the build I got the error that the directory does not exist

it sounds like you have rbenv installed in a different location. update the first part

~/.rbenv

to be the path where you installed rbenv

How to find the location where rbenv is installed ?

sorry, i’m not too familiar with linux but i’d try searching online for ways to find out where you installed it

@Cody that’s it I success to install ruby 3.0 but now I can’t deploy the app through heroku

command to search where an app is installed, in ubuntu e.g.
