Cant Update Console

Yes, after the console restarts it says that it cant update the console, because the update is currently unavailable.

Hey Peeta!

Thanks for bringing this issue to us! Sounds like the console would benefit from a Soft Factory Reset (while keeping games and apps).

I recommend trying :How to restart or power cycle your Xbox One console if the issue persists
you may want to consider some of the
How to reset your console to factory defaults on Xbox One options. Keep in mind you will need your Microsoft account primary email address and password to recover your account onto the console after the reset.

If you're unable to get to the dashboard at all to do the factory reset you need to access the Troubleshoot screen by using these steps :

1. Unplug the network cable if you're using a wired network connection.
2. Power off your console, and then unplug the power cord to ensure that the console is completely powered off.
   
3. Wait 30 seconds, and then plug the power cord back in.
4. Press and hold the BIND button (located on the left side of the console) and the
   EJECT button (located on the front of the console), and then press the
   Xbox button on the console.
5. Continue holding the BIND and EJECT buttons for 10-15 seconds.
   
6. Listen for two “power-up” tones a couple of seconds apart. You can release the
   BIND and EJECT buttons after the second power-up tone.

From there you can reset your console.

Hope this helps

You can try to read this Update Troubleshoot here https://support.xbox.com/en-US/xbox-one/console/system-updates-solution . But for what I can understand about your update error you will need to install the update offline.

Have you done the network settings and console cant update?

Keep in mind offline update cant be done on insiders consoles
