Actualice CentOS 8 a CentOS Stream

Como todos saben, CentOS 8 alcanzó su EOL el 31 de diciembre de 2021, es hora de actualizar su CentOS 8 Linux a CentOS Stream, que es el futuro del Proyecto CentOS. CentOS ha cambiado su enfoque de CentOS a CentOS stream, que es un flujo intermedio entre Fedora y RHEL. Si planea actualizar CentOS 7 a CentOS 8, entonces es mejor omitir la actualización a CentOS 8 ya que CentOS 7 recibirá soporte hasta 2024. Si es inevitable actualizar, actualice a CentOS Stream como se indica a continuación:

Paso 1: Actualice su CentOS 8 a la última versión

# dnf update -y

Paso 2: Compruebe la versión del sistema operativo

# more /etc/redhat-release
CentOS Linux release 8.5.2111

Paso 3: Actualice al último paquete de lanzamiento de CentOS Stream. Esto hace que su sistema busque el repositorio de CentOS Stream en lugar del repositorio de CentOS 8.

# dnf install centos-release-stream -y --allowerasing

CentOS Stream release 8

¡Eso es todo! ¿Le preocupa la vida útil de CentOS Stream? Luego, cambie a una distribución diferente, como Rocky Linux, AlmaLinux u Oracle Linux, que proporciona SOPORTE A LARGO PLAZO (LTS).

Por otro lado, ¿instaló CentOS 8 y se quedó con el error "Error al descargar los metadatos para el repositorio"? Aquí hay una solución.
