When building an image using Yocto Rocko, and meta-openembedded layer building protobuf fail with the following error:
WARNING: protobuf-3.4.1+gitAUTOINC+b04e5cba35-r0 do_fetch: Failed to fetch URL git://github.com/google/protobuf.git;branch=3.4.x, attempting MIRRORS if available ERROR: protobuf-3.4.1+gitAUTOINC+b04e5cba35-r0 do_fetch: Fetcher failure: Unable to find revision b04e5cba356212e4e8c66c61bbe0c3a20537c5b9 in branch 3.4.x even from upstream ERROR: protobuf-3.4.1+gitAUTOINC+b04e5cba35-r0 do_fetch: Fetcher failure for URL: 'git://github.com/google/protobuf.git;branch=3.4.x'.
