  make: *** [Makefile:274: manifest] Error 2

Start by reproducing the Attended Sysupgrade request for profile tplink,archer-c7-v5 and inspect the imagebuilder manifest targets reported at Makefile lines 189, 154, and 274. Trace why firewall4 selects both nftables-json and nftables-nojson; done means the firmware image builds without the package file-clash error.
