Hello @Herve_Grab, welcome to the forums.
Have you tried the workaround in this article?
Hi Mike I’m experiencing the same issue of Herve.
I’ve already tried the workarund without any success 
Some people have been able to solve this by tethering their PC to a mobile phone and then downloading the update.
i connected the laptop to the phone and it worked for me. Thank you!
Hi hope it will be ok also for Herve.
