O Gnome-shell não tem um release candidate [duplicado]

Question

Não consigo instalar o gnome-shell no Ubuntu 17.04. O que estou perdendo?

» sudo apt install gnome-shell

Package gnome-shell is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'gnome-shell' has no installation candidate

    

Answer 1

Eu consertei instalando algumas dependências ausentes como:

apt install gir1.2-*
apt install gjs
apt install caribou
apt install gnome-backgrounds

    

Answer 2

O pacote que você está procurando é ubuntu-gnome-desktop
