Não consigo instalar o Pantheon Greeter no Ubuntu 14.04

Question

Eu quero instalar o panteão Greeter do Elementary OS no Ubuntu 14.04. Quando eu acompanho todos os tutoriais na Web, eu os vejo no Terminal:

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.

The following information may help to resolve the situation:

The following packages have unmet dependencies: 

pantheon-greeter : Depends: libgranite3 (>= 0.2.0) but it is not going to be installed
E: Unable to correct problems, you have held broken packages.*

O que está acontecendo?

    

Answer 1

Na minha pesquisa libgranite3 (> = 0.2.0) não disponível para 14.04

consulte aqui

Portanto, antes de instalar o pantheon , precisamos adicionar o seguinte PPA (que instalará o libgranite3):

Abra o terminal e execute os seguintes comandos no terminal

sudo add-apt-repository ppa:elementary-os/daily
sudo add-apt-repository ppa:elementary-os/os-patches
sudo apt-get update
sudo apt-get install pantheon-greeter

Nota : remova os PPAs após a instalação
