Error: Impossible package selection -> libustream-ssl

Hello,
this is the second time I'm trying attended sysupgrade. But it fails on my NanoPi R2s and my Archer C7 V5 with the same error ...

Collected errors:

• check_data_file_clashes: Package libustream-mbedtls20201210 wants to install file /builder/build_dir/target-aarch64_generic_musl/root-rockchip/lib/libustream-ssl.so
  But that file is already provided by package * libustream-wolfssl20201210
• opkg_install_cmd: Cannot install package luci-ssl.
  make[2]: *** [Makefile:189: package_install] Error 255
  make[1]: *** [Makefile:154: _call_manifest] Error 2
  make: *** [Makefile:274: manifest] Error 2

Reproduce the reported attended sysupgrade request for the NanoPi R2s or Archer C7 V5 and start with the package-install failure in Makefile:189. Trace how luci-ssl selects libustream-mbedtls20201210 while libustream-wolfssl20201210 is already present, then review the surrounding manifest failure at Makefile:154. Done means the listed package set can be generated without the libustream-ssl.so file clash.
