Atualizei recentemente o Ubuntu 14.04 para o Ubuntu 16.04.
Não consigo acessar Configurações do sistema e, portanto, configurações de hora e data, configurações de Bluetooth, etc.
Eu tentei instalar ubuntu-desktop
e isso me deu os seguintes erros:
Reading package lists... Done
Building dependency tree
Reading state information... 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

Eu também tentei instalar unity-control-center

Quando tentei instalar através do Synaptic, ocorreu este erro:
Could not apply changes!
Fix broken packages first.
