Eu gostaria de instalar os drivers para o chip NVIDIA e gostaria de instalar o CUDA para poder programar este chip.
Veja a descrição do meu laptop:

Release Date: 2017.2.14
Operating System: Linux 64-bit
Language: English (US)
File Size: 73.68 MB
A versão do driver 375.39 é o driver que eu deveria usar. Eu ofereço os seguintes cartões:
GeForce 700M Series (Notebooks):
GeForce GTX 780M, GeForce GTX 770M, GeForce GTX 765M, GeForce GTX 760M, GeForce GT 755M, [b]GeForce GT 750M[/b], GeForce GT 745M, GeForce GT 740M, GeForce GT 735M, GeForce GT 730M, GeForce GT 720M, GeForce GT 710M, GeForce 720M, GeForce 710M, GeForce 705M
Seguindo este tutorial : não baixarei o instalador do site. Em vez disso, usarei o PPA.
Como, de acordo com o tutorial, o PPA xorg-edgers fornece os drivers NVIDIA mais recentes, executei os seguintes comandos para configurá-lo:
$ sudo add-apt-repository ppa:xorg-edgers/ppa -y
gpg: keyring '/tmp/tmpikxws_oj/secring.gpg' created
gpg: keyring '/tmp/tmpikxws_oj/pubring.gpg' created
gpg: requesting key 8844C542 from hkp server keyserver.ubuntu.com
gpg: /tmp/tmpikxws_oj/trustdb.gpg: trustdb created
gpg: key 8844C542: public key "Launchpad PPA for xorg crack pushers" imported
gpg: Total number processed: 1
gpg: imported: 1 (RSA: 1)
OK

E: Some index files failed to download. They have been ignored, or old ones used instead.
Primeiro problema : por que alguns dos URLs já incluídos no meu arquivo de origem geram esses erros?
Segundo problema : Na seção Drivers Adicionais da guia Software e Atualizações (ao executar sudo software-properties-gtk), os drivers adicionais devem estar listados e não são ... por quê? Isso estaria relacionado com o primeiro problema?
Neste ponto, acredito que devo ver os drivers listados, antes de tentar uma abordagem alternativa para instalar os drivers:
# Install 375 driver
$ sudo apt-get install nvidia-375
Alguma ajuda para resolver os dois problemas listados?
Atualize o primeiro problema :
Em exibição:
dpkg --print-foreign-architectures
Mostrou que a arquitetura armhf foi incluída como uma arquitetura estrangeira. Eu removi por:
sudo dpkg --remove-architecture armhf
Depois de fazer isso, eu removi o arquivo sources.list original e substitui por um que se parece com isso (let <codename> = trusty ):
deb http://archive.ubuntu.com/ubuntu <codename> main multiverse universe restricted
deb http://archive.ubuntu.com/ubuntu <codename>-security main multiverse universe restricted
(Que foi gentilmente compartilhado aqui: link ). Fazendo isso, resolveu o problema de falhar repositórios. Minha saída da atualização está limpa agora:
$ sudo dpkg --remove-architecture armhf
ejspeiro@Eduardo-Alienware-14:/etc/apt$ sudo apt-get update
