Start with the imagebuilder package-installation failures reported at Makefile lines 189, 154, and 274, focusing on the missing luci-i18n packages, the libustream provider clash, and luci-ssl failure. Reproduce the request for profile zyxel,nbg6817 on OpenWrt 23.05.5 and trace why package selection permits this combination; done means the firmware image builds without these errors.
