Apt-Get Update: falla al buscar; no se puede conectar a ninguna fuente

22

Me doy cuenta de que hay docenas de preguntas de "actualización de apt-get: falla al buscar" (leí todo lo que pude encontrar), pero mi circunstancia actual es exclusiva de 12.04 y afecta a todas las fuentes; no solo launchpad. Además, he probado varios servidores diferentes en Europa y EE. UU., Así como el "servidor principal" (donde sea que esté) y todos producen el mismo resultado: no puedo conectarme a ninguna fuente de software.

Además, estoy bastante seguro de que el problema se debe a la actualización de 11.10-> 12.04 que realicé esta mañana, ya que las actualizaciones funcionaron inmediatamente antes.

Las actualizaciones del Administrador de actualizaciones funcionaron bien y pude descargar algunas cosas (murmurar) del Centro de software sin incidentes, lo que me hace pensar que puedo conectarme a algún subconjunto de servidores de Ubuntu (sin embargo, varios otros servidores de Ubuntu, como extras) y algunos servidores canónicos se enumeran como 'no se puede conectar').

Aquí está la salida de sudo apt-get update:

Obtuve esto cuando lo ejecuté en una VM porque no le había contado sobre nuestro servidor proxy corporativo.

Sí, la actualización del servidor de nombres funciona y, si funciona, probablemente haya actualizado su configuración de IP para que sea estática y su servidor ya no pueda resolver las URL.

Pruebe lo anterior y, si funciona, reinicie. Si falla después de reiniciar, haga esto:

Edite el archivo de plantilla para resolv.conf. El servidor Ubuntu reconstruye esto en cada arranque.

sudo vi /etc/resolvconf/resolv.conf.d/tail

#add just these two lines >>
nameserver 8.8.8.8
nameserver 8.8.4.4

Luego guarde el archivo y reinicie el servicio:

sudo /etc/init.d/resolvconf restart

8.8.8.8y 8.8.4.4son solo los servidores de nombres de Google. Debería poder agregar sus propios ISP si lo desea. Si no te gusta vi, usa nanoo vim.

Lo descubrí leyendo este artículo . Así que les agradezco la propina.

Agregar opciones de servidor de nombres a /etc/resolvconf/resolv.conf.d/tail no es la solución para nada. Primero, cualquier otra dirección proporcionada a resolvconf tendrá prioridad. En segundo lugar, la configuración del servidor de nombres generalmente tiene que ser dinámica (dependiendo del entorno de red y de las interfaces que estén activas) mientras que el tailarchivo es estático. Más allá de esto, no hay indicios de que el problema informado sea uno de resolución de nombres.

Acabo de encontrar la respuesta aquí . Evidentemente, apt no puede manejar muchas fuentes de software, por lo que pude resolver mi problema deseleccionando todas excepto la que necesitaba para acceder. Sería un verdadero dolor hacer esto con frecuencia, pero es mejor que nada. Desde el sitio:

Desde la pestaña "Otro software", deshabilite todos los repositorios PPA, dejando solo los repositorios oficiales de Ubuntu activos. Habilitar demasiados repositorios PPA (que no son oficiales) puede hacer que su administrador de paquetes se vuelva inestable.

Agregue la línea nameserver 8.8.8.8a su /etc/resolv.conf.

Esto establece servidores DNS alternativos (los servidores DNS públicos ejecutados por Google), en caso de que sea un problema de DNS. Es similar, aunque no idéntico, a esta otra respuesta (que se publicó más tarde, y ofrece un método diferente para esencialmente la misma reconfiguración).

Esto es causado por algunos paquetes de proxy como anon_proxy, pasa todas las conexiones HTTP a través de un proxy local utilizando una variable de entorno. Entonces, para cambiar este entorno de edición / etc / y comentar HTTP_PROXY y http_proxy en las últimas dos líneas.

El mismo problema me trajo aquí. Estoy usando Ubuntu Server 12.04. Ninguna de las soluciones anteriores había solucionado mi problema, así que probé otras soluciones.

Acabo de abrir sources.list en / etc / apt y descubrí que algunas de las fuentes están "restringidas".

Simplemente edite sources.list y elimine el parámetro "restringido" y funciona bien ahora :)

¡Espero que eso también funcione para los demás!

La restrictedsección es una sección oficial en los repositorios de Ubuntu. No lo elimine, a menos que realmente quiera ejecutar software solo FOSS. Ver askubuntu.com/a/251606/88802 . No estoy seguro de por qué funciona para usted, no tiene sentido para mí que haga alguna diferencia.
— gertvdijk
pero ¿cómo es que mi servidor se está actualizando ahora? después de eliminar ese parámetro. ¿algunas ideas?
— RustanTech

No creo que tuvieras el mismo problema. "No se puede conectar a ..." (como en el OP) no tiene ninguna relación con la configuración de la sección del repositorio .
