Thanks Curt, Yauhen answered me an exemple who helped me spot a typo I made. The archive shouldn't point at debian.net/ but at debian.org/, like clearly mentionned in [1]. Doing so fixes both the "503 Service Unavailable" error and the requirement to install the apt-transport-https package. I thus could successfully reinstall my Jessie instance. The backports works as expected (when well configured).
Yauhen complete answer should soon appears on debian-user@ (he sent it to me first by mistake, then re-sent it to the list). I copy paste him in the meantime. He add something important to make all works. If not set, apt-get still doesn't want to load the backports repository. I wonder if it's meant to be a temporary fix or not ? > The last one is actually expired. To work around it, you can create file > /etc/apt/apt.conf.d/10no--check-valid-until with the following content: > Acquire::Check-Valid-Until "0"; It now just feel strange to have the main source on http.debian.net and the backports on http://archive.debian.org. I guess I will update my two-stage procedure to converge in order to grab everything from the archive. Or would it be advisable to still grab the non-backports packages from the mirrors ? I ponder this both 1/ not to add avoidable load to the archive server (who could be handled throught the mirrors network), 2/ speed and bandwidth wise regarding the reinstallation of my instances. What would be recommanded ? My current /etc/apt/sources.list looks like this : > deb http://http.debian.net/debian jessie main > deb http://security.debian.org/ jessie/updates main > deb http://archive.debian.org/debian jessie-backports main Pierre.
