SM Software update failure

Is there anyone familiar with Software update failure (to 4.6.1) when updating from cnMaestro?
Some ePMP devices (ePMP 2000, Force 200, Force 180) present this error when updating.

Do you know the reason and how do solve that?

Hello @Jony_Pedro_dos_Santo,

there can be multiple reasons. It needs investigation. Did you try after to update some SMs manually?

Many of the issues that cause an SM to not update are resolved by first rebooting the SM. A few of the reasons for cnMaestro to not complete an update are with the network itself and there may also be other reasons on the SM for the SM to not update.

In short there is no specific reason but also no specific solution either
