Answer 1

Seu repositório está desatualizado.

Por meio da GUI

1. Abra o centro de software
2. Editar > Fontes de software ...
3. Encontre Download de e selecione Servidor principal na lista suspensa
4. Fechar do centro de software
5. Fazer um sudo apt-get update

Via o CLI

Edite seu /etc/apt/sources.list para refletir isso:

deb http://archive.ubuntu.com/ubuntu/ trusty main multiverse restricted universe
deb http://archive.ubuntu.com/ubuntu/ trusty-security main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
deb http://archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
deb http://archive.canonical.com/ubuntu trusty partner
deb http://extras.ubuntu.com/ubuntu trusty main

Alguns dos espelhos quebram. Eu moro no Paquistão, e o espelho aqui não funciona há anos. Eu uso o servidor principal sozinho.
