A única solução para meu problema foi encontrada aqui. Como resolvo dependências não satisfeitas depois de adicionar um PPA? .Eu apliquei os seguintes comandos:
sudo apt-get update
sudo apt-get install aptitude
então,
sudo aptitude install grive-tools
Como último passo, tive que rebaixar alguns pacotes para atender as dependências. Amostra de processo é fornecida em:
sudo aptitude install grive-tools
The following NEW packages will be installed:
binutils-dev{a} comerr-dev{a} expect{a} grive-tools krb5-multidev{a} libboost-filesystem-dev{a} libboost-filesystem1.54-dev{a}
