Hi, my problem continues. Through synaptic I have cleaned the older kernels. I have got only 2.6.32.28.32 version. When I want install the 10.10 upgrade shows the following message:

No se ha podido calcular la actualización

An unresolvable problem occurred while calculating the upgrade:
E:Error, pkgProblemResolver::Resolve generó cortes, esto puede haber sido causado por paquetes retenidos.

 This can be caused by:
 * Upgrading to a pre-release version of Ubuntu
 * Running the current pre-release version of Ubuntu
 * Unofficial software packages not provided by Ubuntu

Si no se corresponde con ninguno, informe de este fallo sobre el paquete «update-manager» e incluya en el informe los archivos situados en /var/log/dis-upgrade/.

The log /var/log/dist-upgrade/20110207-0815/main.log shows the following:
