Eliminar kernels viejos en SUSE Linux

Cómo eliminar un kernel viejo de un SUSE Linux para liberar espacio.



Hoy he actualizado un SUSE Linux Enterprise Server y el sistema me ha devuelto un error indicando que faltaba espacio en disco para instalar un nuevo kernel:

... (182/184) Installing: kernel-default-5.3.18-59.19.1.x86_64 ......................................................................[error] Installation of kernel-default-5.3.18-59.19.1.x86_64 failed: Error: Subprocess failed. Error: RPM failed: installing package kernel-default-5.3.18-59.19.1.x86_64 needs 76MB on the /boot filesystem

Para hacer espacio, tenía dos opciones:

- Borrar archivos no usados.
- Añadir espacio en disco a la máquina virtual.

He optado por la primera y he eliminado el kernel antiguo:

HOST # zypper purge-kernels Reading installed packages... Preparing to purge obsolete kernels... Configuration: latest,latest-1,running Running kernel release: 4.12.14-150.32-default Running kernel arch: x86_64 Resolving package dependencies...

Tras eliminar el kernel viejo, el nuevo kernel se ha instalado sin problemas:
