Invalid release signature error during install of netboot minimal CD amd64

[Carla Sella]

During install of netboot minimal CD on a Virtualbox VM, I get a Debootstrap error "invalid release signature" see attached screenshots.
I made the installation selecting Italian keyboard, language, mirror and installing on guided HD partitioning.

Does a subsequent test still show this bug, or was it just mirror breakage?

Hello Adam.
Yesterday this happened to me twice. I tried again today but strangely it did not happen again. The iso is the same as yersterday and I did the same things as yesterday.

Right, this just sounds like the mirror you were installing against was broken yesterday for some reason. Closing this bug.
