Tengo una instalación absolutamente nueva de Ubuntu 12.04 en una unidad USB, realizada con la imagen de escritorio de PC de 64 bits (i386). Por "nuevo" quiero decir que todo lo que hice fue eliminar el archivo casper-rw y reemplazarlo con una partición grande para aumentar la persistencia.
(Nota: ya sé que no tendré estos problemas en 14.04 o 15.04; sin embargo, necesito usar una herramienta que solo sea compatible con 12.04, por lo que la actualización no es una opción).
Apto-obtener actualizaciónda las siguientes advertencias, pero como son advertencias y no errores, las dejé sin marcar. No son el tema de mi pregunta, a menos que sean parte del problema, pero se proporcionan en caso de que sean importantes. La solución autoinformada por el sistema (ejecutar apt-get update) es obviamente incorrecta porque eso es lo que generó los errores.

No sé qué hacer cuando las actualizaciones salen mal hasta ese punto en un sistema nuevo; Ni siquiera estoy seguro de cuáles son la mayoría de esas cosas.
(Editar: la herramienta a la que hice referencia anteriormente es Nvidia Nsight Eclipse con el propósito específico de realizar una compilación cruzada de código con mi computadora portátil como host y una placa de desarrollo Nvidia Jetson como objetivo. Tengo entendido que solo se admite Ubuntu 12.04).

Desitio web oficial de Nvidia:La última versión de NVIDIA Nsight Eclipse Edition compatible con CUDA C/C++ y compatible con plataformas MAC y Linux. Simplemente instale CUDA Toolkit y ejecute 'nsight' en la línea de comando.
Compruébalo con:
apt-cache policy nvidia-cuda-toolkit
Se enumeran los paquetes incluidos.aquíuno de ellos como puedes vernvidia-nsight: Edición NVIDIA Nsight Eclipsey se mantiene para todas las distribuciones Ubuntu compatibles actualmente.
Para instalar nvidia-cuda-toolkiten la terminal ejecute:
sudo apt-get install nvidia-cuda-toolkit
