Build D-Link DWR-921 C3 - Cannot install package libustream-openssl

Hello fellows,

I am trying to build D-Link DWR-921 C3 and did

make menuconfig

and added some packages to .config and did

make defconfig

Somehow the build fails because of

Package libustream-openssl20200215 wants to install file ...
But that file is already provided by package * libustream-wolfssl20200215
opkg_install_cmd: Cannot install package luci-ssl-openssl.

My understanding was that after

make defconfig

eveything should be fine and dependencies are met.

In the .config I see both:


Do I need to disable one of them manually? If yes, which one?

Cheers, Frood
