¿Por qué apt-abortar por sí mismo, como si hubiera presionado ‘N’?

En Ubuntu 14.04, cuando bash instalar una aplicación o incluso simplemente hago:

sudo apt-get upgrade 

Siempre termino con este mensaje al final:

 Do you want to continue? [Y/n] Abort. 

No escribí nada, simplemente se cancela automáticamente.

¿Pueden ayudarme chicos?

======= [Editar # 1 12 de agosto] ======= Aquí he copiado los textos completos de la terminal. He ejecutado el comando 2 aquí, el: sudo apt-get update y luego, después de obtener el resultado, ejecuto el sudo apt-get upgrade

Aquí están los textos copiados de la terminal:

======= [/ end edit] =============

apt-get cancela cuando quiere confirmación interactiva pero no puede leer la entrada de stdin.

Por ejemplo, cualquier persona (con actualizaciones pendientes) puede reproducir este comportamiento redireccionando / dev / null a stdin:

 skath@tahiti:~$ sudo apt-get upgrade < /dev/null Reading package lists... Done Building dependency tree Reading state information... Done Calculating upgrade... Done The following packages will be upgraded: libcgmanager0 1 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. Need to get 29.3 kB of archives. After this operation, 0 B of additional disk space will be used. Do you want to continue? [Y/n] Abort. skath@tahiti:~$ 

Esto nos lleva a la siguiente pregunta, ¿qué está pasando por la entrada estándar cuando estás llamando a sudo apt-get upgrade ? Esa es una pregunta más complicada y puede involucrar su configuración de sudo o el terminal o shell que está usando para invocar el comando ...

O, si solo necesita una solución, puede pasar -y a apt-get para omitir el indicador: sudo apt-get -y upgrade

mi problema fue que intenté ejecutar varios comandos a la vez copiándolos en la consola

 apt-get update apt-get upgrade apt-get dist-upgrade apt-get install build-essential ... 

Llamando a cada comando por separado resolví mi problema
