How to reproduce

Build ruby without libyaml-dev (?). My build was fixed once I run the apt-get command written in https://github.com/rbenv/ruby-build/wiki, which was probably auto-removed when I upgraded Ubuntu 20.04 to 22.04.

There is a similar issue with Red Hat Enterprise Linux 8. To install libyaml-devel package, it needs 'codeready-builder-for-rhel-8-x86_64-rpms' repository enabled. Refer to https://github.com/rbenv/ruby-build/discussions/1976 .

• Status changed from Assigned to Closed

The download feature for libyaml and libffi with extlibs has been removed from Ruby 3.2.0-preview2.

This issue no longer happened.
