Hello,

This is my first time installing Ruby on Ubuntu.

I have installed the rbenv successfully and all.

above is the result as of today, I hope developers just added a few sentences what each does, and which one is the latest reliable version rbenv supports in regard to official version of Ruby at the time of writing.

if anyone knows what above versions mean, please kindly leave a brief explanation.

Thank you in advance

I have installed the rbenv successfully and all.

Hi, you have not mentioned how you have installed rbenv and ruby-build. Did you follow our official installation instructions? Or did you install via apt install? If you installed from Ubuntu's own repositories, the maintainers of rbenv and ruby-build packages in the official Ubuntu repositories have stopped updating these packages, so they are severely out of date. I do not have control over them, so I cannot update them myself.

This is the output of the latest version of ruby-build:

$ rbenv install -l
2.7.8
3.0.6
3.1.4
3.2.2
jruby-9.4.2.0
mruby-3.2.0
picoruby-3.0.0
truffleruby-22.3.1
truffleruby+graalvm-22.3.1

Only latest stable releases for each Ruby implementation are shown.
Use 'rbenv install --list-all / -L' to show all local versions.

Hello @mislav , thank you for getting back on this.

I have followed https://github.com/rbenv/rbenv page, installing it on Ubuntu (latest version).

Sorry for not being clear enough.

I have used the package manager for Ubuntu/Debian

and I went ahead and ran the following two commands as well:

list latest stable versions:

rbenv install -l

list all local versions:

rbenv install -L

which worked exactly as expected, and

install a Ruby version:

rbenv install 3.1.2

I was lost above step:

I understand there may be some lag time which version available through rbenv and which version official Ruby website released, but I was not sure how to install the latest stable version of Ruby, and start coding.

Thank you for taking the time to reply back on this question again!

[mislav]

This is what our installation instructions say for Ubuntu/Debian installation from apt:

Note that the version of rbenv that is packaged and maintained in the Debian and Ubuntu repositories is out of date. To install the latest version, it is recommended to install rbenv using git.

This note is supposed to warn you that if you install rbenv and ruby-build from apt, you will get out of date versions. Perhaps we should update our documentation to note that you should avoid using apt at all for these packages.

I think it's fine if your rbenv version stays installed via apt (that one is not so severely out of date), but you should uninstall ruby-build and install using git instead of apt:

1. First uninstall ruby-build using apt;
2. Then follow the instructions to install ruby-build via git (you should install git first via apt).

Thank you @mislav , will follow this method.
