Collected errors:

• pkg_hash_check_unresolved: cannot find dependency libmagic for keepalived
• pkg_hash_fetch_best_installation_candidate: Packages for keepalived found, but incompatible with the architectures configured
• opkg_install_cmd: Cannot install package keepalived.
  make[2]: *** [Makefile:189: package_install] Error 255
  make[1]: *** [Makefile:154: _call_manifest] Error 2
  make: *** [Makefile:274: manifest] Error 2

Start with the failure at Makefile:189 during package_install and inspect how the imagebuilder package indexes are generated and verified. Investigate why keepalived cannot resolve libmagic or match the configured architecture, then confirm that manifest generation completes successfully for the reported ipq40xx/generic build.
