What happened?

When spawning fish shell, there is a bluefin motd showing a few commands that we can use, among them is ujust --choose, however, running it gives this error

error: chooser `fzf --multi --preview 'just --unstable --color always --justfile "/usr/share/ublue-os/just/00-entry.just" --show {}'` failed: exit status: 127

Steps to reproduce

1. run ujust --choose on a fresh install

Affected area

just recipes / ujust

Extra context

Maybe this motd is not meant to be displayed, but it does when using fish.
