Você provavelmente removeu o kubuntu PPA sem fazer downgrade de outros pacotes. Para fazer isso, adicione-o novamente e execute:
sudo apt-get install ppa-purge
sudo ppa-purge ppa:kubuntu-ppa/backports
Enquanto fazia sudo apt-get autoremove , acidentalmente apaguei o ubuntu-desktop. Ter o KDE instalado, mas gostaria de trocá-los por razões diferentes (unidade - trabalho, kde - navegar na net). Então, ao tentar instalar o ubuntu-desktop, eu tenho esta saída:
tukanoid@tukanoid-Inspiron-5545:~$ sudo apt-get install ubuntu-desktop
[sudo] password for tukanoid:
