I've upgraded to Debian buster

I’ve upgrade to Debian Buster (latest stable), and now nothing works. :frowning:

ruby was upgraded to 2.5

ruby --version
ruby 2.5.5p157 (2019-03-15 revision 67260) [x86_64-linux-gnu]

I’ve cleared out my gems directory to see if I could reinstall from scratch all here’s what I get

gem install jekyll bundler

bummer, any ideas? (I really don’t want to go back to Stretch)

Has no one else tried installing jekyll in buster (or sid, previously) ?
