From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I forgot about PPAs - I don't normally use Ubuntu-derivatives. PPAs are a little more dangerous if I recall correctly right? Firstly it should be an official PPA from the software developer, and secondly because it's a repo you have to make sure that it isn't going to eventually pull in packages that replace/break your system.
Safety for the ones I've listed:
/home installation
/home installation
with local dependency network/home installation
/home installation
Worst thing about PPAs is their maintainers don’t keep up with the base Ubuntu version and then you have to disable the PPA on the next version upgrade, or you end up seeing someone with repositories for Ubuntu 16.04 on 22.04 and wondering why apt is returning errors. Containers are a much better modern solution.
