I wonder why I couldn't reproduce this with the 12.9 netinst then. You would think that there's far more reason to insist on preferring http: over cdrom: when so little is available on the installation medium, compared with a 12.9 DVD. I configured the network, used it to configure the clock, installed the base system, configured the package manager with no mirror, included the security/release updates, accepted standard system utilities, and all the packages (far fewer than normal, of course) were then installed from cdrom:—nothing from http:. I aborted at the Grub question. So can you explain the intended logic here, particularly as you say we're not expected to be able to reason it out. > > Jan 31 05:35:42 in-target: Get:1 > > http://security.debian.org/debian-security bullseye-security InRelease > > [27.2 kB] This is what I can't replicate when "Use a network mirror?
