Friends - I looked and wasn't able to find a digital signature for the SHA256SUMS file in http://ftp.debian.org/debian/dists/bullseye/main/installer-armhf/current/images/ or http://ftp.debian.org/debian/dists/bookworm/main/installer-armhf/current/images/
There _are_ signatures provided for CD images at https://cdimage.debian.org/debian-cd/current/armhf/iso-cd/ but that's not the normal installation process for the gazillion armhf SBCs. I'm pretty sure most people are like me, and use the process documented in "5.1.5. Using pre-built SD-card images with the installer" at https://www.debian.org/releases/bullseye/armhf/ch05s01.en.html or https://www.debian.org/releases/bookworm/armhf/ch05s01.en.html Am I blind? Can the process be adjusted to generate such a signature file? - Larry
