Problem solved, at least for me. This is how, thanks to the Apple chat support:


  1. System settings -> Networks -> Wi-fi: select the network you're logged on
  2. Press on "Details"
  3. Go to DNS (left hand menu)
  4. Change the DNS servers (press on +):
    1. Lign 1: 8.8.8.8
    2. Lign 2: 8.8.4.4
  5. Start again the update


And make sure to have no VPN on.


Good luck
