UnsatisfiableError for conda uninstall libprotobuf

[za13]

I am using Ubuntu and tried to build Caffe and got a bunch of errors saying this file was generated by an older version of protoc

After doing some research into it, it seems many people resolved the problem by doing

conda uninstall libprotobuf

However, when I tried that, I get this:

	Collecting package metadata (repodata.json): done

Found conflicts! Looking for incompatible packages.

when I type protoc --version, it says libprotoc 2.6.1

can anyone help?

[chenkangyang]

which protoc or where protoc to get the location of protoc.
conda search protobuf or ``conda search libprotobuf` to find satisfied version in your conda channels.

It seems like you dont have protoc in the anaconda path, it makes conda uninstall failed.

Those Package tk conflicts means
some of your conda pkgs conflicts with your python version
Using conda update to update those pkgs. (emmm.. Maybe, Im not sure).

Also im confusing which protobuf version is suitable for caffe1.0 ..?
