It's not unusual to see people talking about android users being Linux users "because android is Linux too" clearly not understanding the difference between Linux the OS, i.e. GNU/Linux, and Linux the kernel. So it's useful when you have to make such a distinction.
Alpine is also arguably not "GNU/Linux", as it doesn't use GNU Core Utils or glibc. But I don't know anyone who would suggest that Alpine isn't "proper Linux".
Unfortunately for them this means that 99.99% of the Linux distributions out there do not qualify as >GNU/Linux, even the ones like Debian, Red Hat, or Ubuntu that did adopt the GNU/Linux name >scheme, because they all host, promote, or allow users access to non-free software in some way.
You are totally confused. In words of R. Stallman:
"The kernel is an essential part of an operating system, but useless by itself; it can only function in the context of a complete operating system. Linux is normally used in combination with the GNU operating system: the whole system is basically GNU with Linux added, or GNU/Linux. All the so-called “Linux” distributions are really distributions of GNU/Linux".
"Today there are many different variants of the GNU/Linux system (often called “distros”). Most of them include nonfree programs".
It was a dependency resolution issue. Npm couldn't install one of the packages without some package.json gymnastics, and those same gymnastics somehow fucked with our debian based images that we use for development. I can't say much more because I honestly don't know what exactly happened. I just diagnosed the issue and forwarded it to our resident node guru, who took it from there.
