Ok

but how long does it take to update

That would depend on internet speed, file size, etc ….. to many factors to give an accurate time frame. However, it will not update while that error message is present.

Is the device connected to a Wifi network?

Is the device fully charged, and preferably connected to the charge circuit?

Could you please post a screenshot of the message that appears when you attempt to update?
