tips

Remove pkg_postinst_ontarget:${PN} from .bbappend:

pkg_postinst_ontarget is variable, not task. Task emit_pkgdata() is processing pkg_postinst_ontarget variable and adds content of variable as a postinstall script in deb package.

# This will remove script at all:
pkg_postinst_ontarget:${PN} = ""
 
# This will replace body of script with exit 0
pkg_postinst_ontarget:${PN} () {
    exit 0
}

Disable SPDX to save build time:

INHERIT:remove = "create-spdx"
