Missing ubuntu packages

I am trying to install packages such as fd-find and hexyl, which are in the ubuntu repos since Ubuntu 20, but these are nowhere to be found. Are the normal ubuntu repos not compatible with Zorin?
I found hexyl as a snap, but that has issues with permissions due to confinement.

archive.ubuntu.com/ubuntu/pool/universe/r/rust-hexyl/hexyl_0.6.0-2build1_amd64.deb

I also have this issue. distrobox package is missing from the repos even tho it's in the Ubuntu one.

Distrobox is in the Ubuntu Noble repository: Ubuntu 24.04.
It is not present in the Jammy repository: Ubuntu 22.04.

That said, you can safely install it using the available .deb package from the repository. Copy this link and paste it to your browser:
http://archive.ubuntu.com/ubuntu/pool/universe/d/distrobox/distrobox_1.7.0-1_all.deb

Then use Gdebi, software installer or terminal

sudo dpkg -i distrobox_1.7.0-1_all.deb

to install.
