Start with the supplied ASU request for profile zte,mf286d and its image-builder stderr, focusing on the conflicting libustream-mbedtls and libustream-wolfssl providers and the luci-ssl installation failure. Reproduce the attended sysupgrade request and trace package selection; done means the requested firmware image builds successfully without that conflict.
