By that thinking "The need to use something like APT/YUM/DEB/RPM to distribute a complex application is a good indication you've built something which is a mess, and probably should be rethought from first principles."

So Linux is a mess? And we should rethink how rpm and deb work?

Or all Deb issues go away if you stop using Linux?

People forget that Helm is a package manager first and foremost (the only one for Kubernetes). It also happens to include a templating mechanism. The templating part has its issues, but until we find another package manager, I don't see Helm going anywhere.
