Cannot install ruby with asdf on ubuntu

I encountered an error when installing ruby on my Kubuntu 22.04 using asdf.
When I ran this code
asdf install ruby 2.6.4
The terminal show this and stopped forever:

Please help!

I tried some different tag with openssl like ASDF_RUBY_BUILD_VERSION=master asdf install ruby 2.6.4 or RUBY_CONFIGURE_OPTS=--with-openssl-dir=/opt/openssl-1.1.1n asdf install ruby 2.6.4 but not working too.

Pay attention to these parts:

The problem is not that Ruby will not compile and that's why the flags you added did not change anything. The problem is that Ruby can't be downloaded at all.

You need to ensure that:

1. The remote host cache.ruby-lang.org is online
2. The remote host cache.ruby-lang.org is reachable from your computer

You can try downloading the file directly with curl:

curl -O https://cache.ruby-lang.org/pub/ruby/2.6/ruby-2.6.4.tar.bz2

You should see output like this:

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                                 Dload  Upload   Total   Spent    Left  Speed
100 13.7M  100 13.7M    0     0   9.9M      0  0:00:01  0:00:01 --:--:--  9.9M

And you should have the file ruby-2.6.4.tar.bz2 downloaded as a result. If not then the problem is either 1 or 2 above, and you need to ensure that you are not blocking connections to cache.ruby-lang.org.

Update! I figured it out by this command: CFLAGS="-Wno-error=implicit-function-declaration" asdf install ruby 3.2.0.

If there's any error, try pre-install these libs: sudo apt install libyaml-dev libssl-dev.
