Bom pelo que entendo ele iria baixar de internet e dos repositórios do ubuntu o nvidia-glx-new. Procure por ele no Synaptic (menu Administração > Sistema> Gerenciador de pacotes Synaptic) pelo botão procurar e se encontrar clique com o botão direito sobre ele e escolha a opção marcar para instalação e depois clique no botão aplicar.
Pesquise aqui no fórum sobre o Envy que é um programa que visa automatizar a configuração de placas de vídeo ATI e Nvidia.
Não existe essa opção nvidia-glx-new no Synaptic. Já baixei o Envy, agora vou procurar um tutorial de como utilizá-lo.
Até mais...
Amigo penso que o seu arquivo que contém a lista de repositórios do Ubuntu ( sources.list) esteja com algum problema, pois fui ao Synaptic e procurei por
nvidia-glx-new e encontrei estes dois pacotes:
-

sources.list que se encontra em
/etc/apt/. No terminal seria assim:
sudo gedit /etc/apt/sources.listPara adiantar serviço o conteúdo original do arquivo
sources.list seria esse aqui:

Se realmente estiver errada e você alterar para a correta, após a mudança e ainda no terminal digite:
sudo apt-get updatepara atualizar o banco de dados dos repositórios e logo em seguinda use o
Grenciador de drivers restritos para baixar o pacote necessário para sua placa de vídeo. talvez o erro seja por que sua sources.list está com algum tipo de erro.
