O primeiro comando que você executou está correto!
Ele afirmou que ubuntu-desktop já está instalado - você precisa selecioná-lo na sua tela de login do Kubuntu.
Estou tentando instalar o desktop gnome do kubuntu. Então eu fiz isso: sudo apt-get install ubuntu-desktop correu bem, mas agora eu estou recebendo este erro:
sudeep@sudeep:~$ sudo apt-get install ubuntu-desktop

ubuntu-desktop is already the newest version.
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
firefox-globalmenu : Depends: firefox (= 20.0+build1-0ubuntu0.12.10.3) but it is not going to be installed
firefox-gnome-support : Depends: firefox but it is not going to be installed
lightdm-remote-session-uccsconfigure : Depends: firefox but it is not going to be installed
xul-ext-websites-integration : Depends: firefox (>= 9.0) but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Ele afirmou que ubuntu-desktop já está instalado - você precisa selecioná-lo na sua tela de login do Kubuntu.
Remova o pacote kubuntu-firefox-installer .
Verifique se você tem repositórios Universe e Multiverse habilitados.
$ su -
# nano /etc/apt/sources.list
Exemplo de saída do Xubuntu 12.04, que é preciso, certifique-se de que a linha esteja descomentada, com o nome da versão correta.

Depois de ter certeza que você ativou os repositórios Universe e Multiverse em /etc/apt/sources.list, agora podemos instalar o gnome.
# apt-get update
# apt-get install ubuntu-desktop
ubuntu-desktop instalará softwares completos de adição de desktop gnome como firefox, libreoffice, rhythmbox. Se você quer apenas o ambiente de desktop gnome limpo sem esses softwares, você pode executar este comando.
# apt-get update
# apt-get install ubuntu-desktop --without-recommends
funciona para mim link
