i want to inform you that Repology has your "repository" of software versions included and can list problems or outdated versions that way.

You might want to give that information to the maintainers of this data set. I havn't found a portal or place for related informations.

It is probably possible to automatize this somehow. Just ask a human for source link that package actually has that version now or scrape the projects download page for that version string and use that.

Are you interested to import data from there? Like when a version is available in more than 10 repositorys trust and import it. You can ask for such a feature (with compatible license) here: https://github.com/repology/repology

I hope that helps you to make Wikidata better. It's a great project!

kind regards
