Description of the problem / feature request / question:

I am trying to install bazel using choco on windows machine which in turn tries to install some more dependencies - msys2 and bazel. It throws some error messages for which I am not sure.

choco install bazel

I executed above command using administrative rights on windows machine. Here are the logs:

D:>choco install bazel --force

It looks like you suffered network issues during the downloads. Does this happen if you retry, and/or try a different network?

Log bits that make me think this:
