On CachyOS (Arch-based), Gentle AI 2.2.0 fails during "Install Zsh" because it runs:

[YeshuaCM]

sudo pacman -S carapace

carapace is no longer available in the official Arch/CachyOS repositories (pacman -Ss carapace returns nothing), causing the installation to abort.

[gerardo-lopez-dev]

Same error. Fedora kde plasma

[adrianmoris]

I remember that, to fix this problem, you have to install it from AUR, because Carapace isn't available directly in the repositories via pacman.
