Install Failed - Linux Mint 21.3 on a MacPro5,1

[JHPGuy]

Hello Team. I've had the same error on this system with several Linux distributions - Mint 21.2, Mint 21.3, Neon latest. As the "quick install" technique reaches the end of the install, I get this -
Usage:
pip3 install [options] [package-index-options] ...
pip3 install [options] -r [package-index-options] ...
pip3 install [options] [-e] ...
pip3 install [options] [-e] ...
pip3 install [options] <archive url/path> ...

no such option: --break-system-packages

Kinto install has failed.

cd into ./xkeysnail
Run 'sudo pip3 install --upgrade .' to debug issue

I did run the pip3 install referenced above, but I'm not sure what to do with that.
Thanks for the help!
Josh
P.S. I have Kinto successfully running on 2 other systems, so I have been able to get this working in the past.

I re-ran the "quick install method" and it installed correctly, and Kinto is now working correctly.
I guess the "sudo pip3 install --upgrade ." upgraded pip3, and now everything worked. Or something.
Maybe it's helpful for future users to see this post.
Sorry to take your time.
Still LOVE this tool.
Thanks so much!
Josh

+1 Just ran into this same issue on Elementary OS 7.1. Clean install of Kinto. Had to cd ~/Downloads/kinto-master/xkeysnail and then sudo pip3 install --upgrade . before rerunning the quick install command.
