I solved this on my computer and maybe it can help you. My environment is Ubuntu16.04, and I installed Anaconda(for python2.7) before I install Caffe. It happens that I used conda to install libprotobuf-dev, and this leads to conflict with the caffe's 'sudo
apt-get install libprotobuf-dev' command, for 'apt-get' and conda installed different on my computer which can be find by 'locate protobuf', so I remove the Anaconda's version of libprotobuf, and no problem happens again.

conda uninstall libprotobuf

When you install tensorflow before install Caffe, this problem will also happen, because of the libprotobuf conflict.
