In the last days we've found twice that, when uploading tarballs with lookaside_upload to new branches, the permissions are incorrectly set and the script fails with:

/tmp/scratch_dir/centos-git-common/lookaside_upload -f SOURCES/msgpack-1.0.4.tar.gz -n python-msgpack -b c9s-sig-cloud-openstack-zed

Debugging it, we found it that we get 403 error from https://git.centos.org/sources/python-msgpack/c9s-sig-cloud-openstack-zed/

Fabian checked that the permissions are wrong and set them properly manually.

We've hit this with both python-msgpack and python-textfsm but not for other packages where we've also created new branches so it seems there is some randomness.
