Unable to upgrade to lastest SNAPSHOT version

Trying to upgrade Netgear WNDR3800CH using Luci Attended-sysupgrade
From: OpenWrt SNAPSHOT r27279-8b6c63cfaf / LuCI Master 24.212.79282~65b8002
To: SNAPSHOT - r28199-1bdb6d8404

If I add OPKG as a dependency it throws this error
NOTE: opkg is NOT available anywhere in https://downloads.openwrt.org/snapshots/packages/mips_24kc/

Start at the ASU request handling and package-index generation path for the reported sysupgrade request. Reproduce the SNAPSHOT build with profile netgear,wndr3800ch and the opkg dependency, then trace why the packages index is missing; done means the requested image builds successfully with that dependency.
