> If that package doesn't exist, Gentoo's portage has a system where it suggests "similar" sounding packages. Like if you try to emerge "firebox" instead of "firefox" it will offer it as a correction
This exists in Ubuntu/Debian - if you type `firebox` you literally get:
$ firebox
Command 'firebox' not found, did you mean:
command 'firefox' from deb firefox (1:1snap1-0ubuntu2)
Try: sudo apt install <deb name>
Even that is really a function of the shell and not the distribution itself.
Is that if you try to run the command, or install the package?
