sudo apt-get update failing in ubuntu 12.04

Question

I am trying to update apt-get in order to install salt-minion but I am getting the error GPG error: http://repo.saltstack.com precise Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 0E08A149DE57BFBE so I am not able to update and then install what I need

Run sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 0E08A149DE57BFBE
And then sudo apt-get update

First Way:

Try adding missing key:

     sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 0E08A149DE57BFBE

Then do update:

     sudo apt-get update

Second Way:

If its a useless package then try removing from /etc/apt/sources.list and from this folder:

cd /etc/apt/sources.list.d
