Um tempo atrás eu atualizei para o Ubuntu 15.04 e brinquei com alguns temas. Agora tenho problemas para reinstalar o Unity;
$ sudo apt-get install --reinstall ubuntu-desktop
Reading package lists... Done

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:
ubuntu-desktop : Depends: ubuntu-session but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
Eu então tentei instalar o ubuntu-session e obter esta resposta:
ubuntu-session : Depends: gnome-session-common (= 3.14.0-2ubuntu4) but 3.14.0-2ubuntu5 is to be installed
Alguma ideia sobre o que fazer? Não tenho certeza se devo apenas forçar a instalação da versão 2ubuntu4. Por favor, note que eu tenho que tentar atualizar pacotes, limpeza de cache, etc.
