Luci packages missing 19.07.6 mips_24kc

Tried to upgrade packages on my router today, and found out that most of the luci packages are missing in directory https://downloads.openwrt.org/releases/19.07.6/packages/mips_24kc/luci/ .

Since 19.07.7 is out now, you'd better install that, rather than upgrading your packages.
