Eu tenho uma instalação absolutamente nova do Ubuntu 12.04 em uma unidade USB, feita usando a imagem do PC (i386) Desktop de 64 bits. Por "fresco", quero dizer que tudo que fiz foi remover o arquivo casper-rw e substituí-lo por uma partição grande para aumentar a persistência.
(Observação: já sei que não terei esses problemas no 14.04 ou 15.04; no entanto, preciso usar uma ferramenta que só seja suportada no 12.04, portanto, a atualização não é uma opção.)
Atualização do apt-getfornece os seguintes avisos, mas como são avisos e não erros, deixei-os desmarcados. Eles não são o assunto da minha pergunta, a menos que façam parte do problema, mas são fornecidos caso sejam importantes. A solução auto-relatada pelo sistema (executar apt-get update) está obviamente errada porque foi isso que gerou os erros.

Não sei o que fazer quando as atualizações dão errado até esse ponto em um sistema novo; Eu nem tenho certeza do que são a maioria dessas coisas.
(Editar: a ferramenta que mencionei acima é o Nvidia Nsight Eclipse para o propósito específico de compilação cruzada de código com meu laptop como host e uma placa de desenvolvimento Nvidia Jetson como alvo. Meu entendimento é que apenas o Ubuntu 12.04 é suportado.)
