DistroBox

DistroBox is like Winboat (like I mentioned in Virtual Machines) only for Linux. If you want to try a package manager from another distro or there's a package only available on another distro, DistroBox simply lets you install it to your distribution in a line or two of text pasted into terminal.

This means that every distribution's software is available on every distribution. This is MASSIVE and I highly recommend making use of it once you've learned the basics. If something you're looking for is only on one distro or just isn't on yours just use DistroBox! (there's also tools that make using DistroBox easier available in Flatpaks).
