¬ just serendipity 🍀 (not just serendipity)

Upon upgrading one of our Dockerfiles from Alpine Linux 3.21 to 3.22, we noticed that the ruby-json package no longer exists:

% docker build -t myproject -f Dockerfile .
[...]
 > [ 2/10] RUN apk add --update --no-cache ruby-json=~"3.4" [...]
[...]
2.371 ERROR: unable to select packages:
2.371   ruby-json (no such package):
2.371     required by: world[ruby-json~3.4]

Why??

First, look into Alpine Linux Packages: query. Ensure to set branch to v3.22 and architecture to All. And it’s indeed not there anymore:

No matching packages found…

Next, do a bit of digging in the aports repository on the Alpine Linux GitLab: query. Search for ruby-json in “All” Merge requests.

That leads to !80599:

community/ruby-json: remove

ruby-json is already bundled with main/ruby. The community/ruby-json could never be installed due to conflicts.

Aha, then there’s nothing to do here. Installing the base ruby package should be enough from now on.

#16938:

I think it’s safe to say community/ruby-json does literally nothing, has never been installed, and does not work.

Oh well.
