Al intentar cargar /admin/docker/repos Código de error: 500

Milenski · 8 Enero, 2026 03:26

¿Qué está pasando con Discourse? Cuando intento cargar la página de administración para una actualización, obtengo este error: “al intentar cargar /admin/docker/repos Código de error: error 500”.

Recuerdo que esto sucedía cuando se implementaba un nuevo plugin y también se instalaba en el sistema. Pero ahora no tengo ninguno instalado, y solo uso los implementados.

Completé:

cd /var/discourse
./launcher rebuild app

Y todo transcurrió sin problemas, pero el mismo error vuelve a ocurrir para la página de actualización en el panel de administración.

También dejaré un backtrace de /logs aquí:

Agradecería mucho si alguien sabe algo sobre el tema y puede ayudar.

Gracias por los informes. Tengo una solución en proceso:

Publicaré de nuevo aquí una vez que esté disponible en latest

Mismo error aquí después de instalar las actualizaciones hoy, la reconstrucción no ayudó.
Las actualizaciones se instalaron bien ayer y nunca antes había visto este error.

Yo también tengo este problema, reconstruir dos veces no lo solucionó, esperando una corrección.

david · 8 Enero, 2026 14:59

Disculpe la demora; tuvimos algunos problemas no relacionados con nuestro CI hoy.

La corrección ya está activa en latest, por lo que actualizar de nuevo debería resolver el problema. Por favor, háganos saber si no es así.

Confirmo, el problema está solucionado. Después de una reconstrucción a través de la terminal, todo está bien. Gracias.
