Oxide.Ubuntu is an experimental module - future versions may change in backwards-incompatible ways, and without bumping the module version. Please use with caution

[libprotobuf FATAL ../../third_party/protobuf/src/google/protobuf/stubs/common.cc:78] This program was compiled against version 2.6.1 of the Protocol Buffer runtime library, which is not compatible with the installed version (3.0.0). Contact the program author for an update. If you compiled the program yourself, make sure that your headers are from the same version of Protocol Buffers as your link-time library. (Version verification failed in "/build/mir-sajBv9/mir-0.26.1+16.04.20170209.1/obj-x86_64-linux-gnu/src/protobuf/mir_protobuf.pb.cc".)
