You don't mention how you are using unzip.

If you are including unzip in your image then failing to download it
during fetchall is unexpected and sounds like a bug.

If you're not including unzip in your image but instead your build
actually depends on unzip-native (ie a tool to run on the host and
needed as a build dependency if a recipe you build contains .zip or
.jar files in SRC_URI) then I'm not sure what the expectation is. If
fetchall doesn't download these indirect -native dependencies then it
might just be the way it is. If so, then manually running "bitbake -c
fetch unzip-native" might be an appropriate solution.
