> I don’t see why the package manager should prevent using it with another library that depends on a different version. I do. The main reason for Linux distributions to exists is to provide a development and running environment where: - API/ABIs do not change for the whole lifetime of the distribution. No new features, no new bugs, no new vulnerabilities, so that your production code can run reliably for 5+ years. - Vulnerabilities are fixed with minimally invasive patches. - Vulnerabilities are fixed in reasonable times even if the upstream development stopped. Patches are well tested against the set of packages in the distribution. You simply cannot have these 3 features together if a distribution ships 10 different version of each library. It's already a ton of work to maintain packages in stable distributions.
