Arch Linux fix

First, grab the missing menu package:

sudo pacman -S archlinux-xdg-menu

Make it permanent (by shell)

For Fish:

set -Ux XDG_MENU_PREFIX arch-
kbuildsycoca6 --noincremental

For Bash/Zsh:

Add to your ~/.zshrc or ~/.bashrc:

export XDG_MENU_PREFIX=arch-

Then run:

source ~/.zshrc  # or ~/.bashrc
kbuildsycoca6 --noincremental

The “Global” fix:

Add to /etc/environment

XDG_MENU_PREFIX=arch-

And that’s it
