Installing 3.3.2 fails on debian trixie - libncurses5-dev has unmet dependencies

[robacarp]

First off, this tool is amazing and has been amazing for years. Thank you.

Description

This is absolutely not a problem with ruby-install, but I hit the snag while using ruby-install so someone else might too. Perhaps it's something ruby-install can work around, but maybe not.

Steps To Reproduce

ARG RUBY_VERSION=3.2.3

FROM seleniarm/standalone-chromium

USER root

RUN apt-get update \
 && apt-get install -y build-essential

WORKDIR /opt
RUN \
  wget https://github.com/postmodern/ruby-install/releases/download/v0.9.3/ruby-install-0.9.3.tar.gz && \
  tar xzvf ruby-install-0.9.3.tar.gz && \
  cd ruby-install-0.9.3/ && \
  sudo make install

RUN ruby-install --cleanup ruby "${RUBY_VERSION}"

Building that dockerfile fails with this error:

The install fails because the dependencies for libncurses5-dev are out of whack somewhere within the debian trixie configuration. It's easy to reproduce without ruby-install with just apt install libncurses5-dev. I don't really know enough about the debian maintainership world to begin to know who to contact about this issue -- probably someone within the curses team, but I'm out of my depth here.

As far as I'm concerned, ruby-install does a gigantic job of making ruby installations dead simple.

Here's what I don't know: Is it possible to work around this with ruby-build (or on my own)? Is that something ruby-install tries to do?

Looks like I should pick a more generic libncurses package name, like libncurses-dev.

That was enough to get me up and running, thank you. I disabled installing deps and ran the apt command manually, but with libncurses-dev instead of libncurses5-dev:

apt-get install -y xz-utils build-essential bison zlib1g-dev libyaml-dev libssl-dev libgdbm-dev libreadline-dev libncurses-dev libffi-dev
ruby-install --no-install-deps ruby 3.3.2

Later:
