today i upgraded to 19.7.6 and tried to install the luci-ddns-package. I got following failure:
Collected errors: * opkg_download: Failed to download http://downloads.openwrt.org/releases/19.07.6/packages/mips_24kc/luci/luci-compat_git-21.018.57536-6ba9740-1_all.ipk, wget returned 8. * opkg_install_pkg: Failed to download luci-compat. Perhaps you need to run 'opkg update'? * opkg_install_cmd: Cannot install package luci-app-ddns.
The requested file is missing in the directory.
