How to be certain of delivery

I’ve had to order a nitrokey laptop with a Qubes OS because I’m a journalist and sometimes have sophisticated groups of people trying to stop me working. When I received my laptop I tried to download some updates via the terminal screen but was unable to deploy the update. This is not usually a problem but I’m aware that these people knew that my download failed. My question is how can they do that if its a brand new machine? I’ve had these people interfere with my packages before, but, in this case when my package arrived it looked in tact? Is there a way of checking serial numbers to ensure I have what was originally sent?

please send a mail to and we can see what we can do

I sent an email on Wednesday and haven’t had a response, can you chase this please?
