ssl version issue - ubuntu 24 cannot install gem with ruby 2.7.6 (rvm)

After upgrading to Ubuntu 24, I can no longer install gems for ruby 2.7.6, here is some output:

rvm list=> ruby-2.7.6 [ x86_64 ]

now I try to bundle

bundleTraceback (most recent call last):    2: from /usr/share/rvm/rubies/ruby-2.7.6/bin/bundle:23:in `<main>'    1: from /usr/share/rvm/rubies/ruby-2.7.6/lib/ruby/2.7.0/rubygems.rb:296:in `activate_bin_path'/usr/share/rvm/rubies/ruby-2.7.6/lib/ruby/2.7.0/rubygems.rb:277:in `find_spec_for_exe': Could not find 'bundler' (2.3.18) required by your /home/kevin-chugh/Documents/code/opencaseware/Gemfile.lock. (Gem::GemNotFoundException)To update to the latest version installed on your system, run `bundle update --bundler`.To install the missing version, run `gem install bundler:2.3.18`

So now I try to install the gem:

gem install bundler:2.3.18ERROR:  Loading command: install (LoadError)cannot load such file -- opensslERROR:  While executing gem ... (NoMethodError)undefined method `invoke_with_build_args' for nil:NilClass

It seems like there is a general OpenSSL version with older rubies, anyone have any idea how to fix this?

Thanks,Kevin
