Machine: Hyper-V / VirtualBox VM Not sure whether this is classified as a Debian Installer or apt problem: I've been creating a customized installation ISO image with a preseed file for several versions. My configuration was working fine until Trixie, i.e. it works in <=Bookworm. I copy a custom sources.list during installation with a late_command: > d-i preseed/late_command string \ > cp /cdrom/custom/conf/sources.list /target/etc/apt/sources.list The sources.list obviously doesn't contain the cdrom entries. This breaks on Trixie, on step "Finish the installation", it will start prompting for an install media in a loop: > Please insert the media labeled '<disk label>' and press enter. > *Media change* According to console output, this is caused by /usr/lib/finish-install.d/08hw-detect: > finish-install: info: Running /usr/lib/finish-install.d/08hw-detect > ... > in-target: E: Unable to locate package hyperv-daemons > load-install-cd: E: failed to mount the cdrom. The virtualization packages (e.g. hyperv-daemons, virtualbox-guest-utils) are not even available on (at least) the DVD1 media? Also, it should be able to find & mount my DVD by label too, because I configure it into $MEDIA/.disk/info (the error message displays the correct custom label for the media) So, both errors appear to be irrelevant. Regardless, as a workaround, I added a preseed early_command: > d-i preseed/early_command string \ > rm /usr/lib/finish-install.d/08hw-detect This fixes the preseed installation. However, this results in virtualization tools and processor microcode packages not installing.
