I recently released a package for rosdistro. This package succesfully builds for amd64 architecture but fails for arm64 and armhf with same error
ERROR: rosdep-modules 0.20.1 has requirement rospkg>=1.3.0, but you'll have rospkg 1.2.6 which is incompatible.
rospkg is now on 1.5 and rosdep installs rospkg on version 1.4 so it's probably safe to say it would work on arm64 at version 1.3, and can probably have this issue closed.
