Using a MacBook Air with CATALINA, I'm trying to create a bootable USB with Yosemite, from a disk image I was able to download from Apple (19-apr-2020). I've already got the App from the PKG file in DMG. I found this Question/Answer (post/article) regarding the issue of creating a bootable UBS for Yosemite, and other OS X versions: https://discussions.apple.com/thread/8534575.
Unfortunately, after following Answer (from apple recommended user), issuing sudo command for Yosemite in Terminal app to create Installer USB, using my Catalina MacBook Air, I got this error: Cub cadet 1325 manual.
The traditional method of creating a bootable OS X USB installer no longer works, so you’ll need to follow a new approach when dealing with OS X Yosemite. While there are multiple methods that will work, here’s the easiest way to create a bootable OS X 10.10 Yosemite USB Installer for the Yosemite Public Beta. Create a Bootable USB Drive with Clover by Jack Nguyen + USB 8GB + Yosemite 10.10.app (Appstore) + Clover: https://www.dropbox.com/s. Learn how to use Disk Utility to create a bootable OS X Yosemite installer on just about any bootable media, including flash drives, and SSDs. The download will create a link in your Applications folder called ‘Install OSX Yosemite’. Don’t open it yet. Doing so will install Yosemite indeed, but it’ll be an upgrade over the top of what you already have and it’ll delete itself after it’s re-installed. This is not what we want if we’re putting it on a USB.

Is there a walk around? I'm stuck here. Any help would be appreciated. Thanks.

PS. I need this Yosemite Install USB for an old MacBook Pro mid 2009 5,4 that reboots using El Capitan recovery utility to reinstall. I need to tell you I've already downloaded and created bootable USB for El Capitan twice, and after a while, the install process finishes with a fail notice for some missing 'appropriate packages', hanging. From there on, only admits rebooting, which I've also tried several times. Starting or rebooting doesn't recognize Shft+Alt+Cmd+R for Internet re install option. That's why I wish to try Alt+R and Yosemite USB for a clean install:
