Hey, all, if you are having issues with `dx/build` due to `lsb_release` not being there, I have updated the [GitHub repo](https://github.com/davetron5000/sidekiq-book) with a fix. The repo also updates to Ruby 3.2.3 and addresses a CVE with puma.

Thus, the book’s `.zip` will be slightly out of date, so try using what’s in GitHub.
