Don't worry it's not your fault it's simply the evolution of OpenWrt and its new apk package manager that replaced opkg.
@qosmio I see that you rebased your repo a few minutes ago. Are there any anomalies with the new apk package manager.
My first attempt to compile with old opkg ended with
Collected errors:
* pkg_hash_check_unresolved: cannot find dependency procd-seccomp for base-files
* pkg_hash_fetch_best_installation_candidate: Packages for base-files found, but incompatible with the architectures configured
* opkg_install_cmd: Cannot install package base-files.

Enabling seccomp resolved the error.
Compiling with apk as default package manager was successful too with a minor fault of uclient-fetch and wget conflicting with each other. So I excluded wget from the build but I left curl.
