You must use higher version number.... e.g. use $ dch -i and use a sensible version number and describe your changes, e.g. use 2016.09.19+namexx1 for version number or similar. Can you paste contents of your ubuntu-keyring_*_all.deb? e.g. output of $ dpkg-deb -c ubuntu-keyring_*_all.deb > apt_ftparchive -c config-rel release cd/dists/yakkety > > cd/dists/yakkety/Release > gpg --yes --no-default-keyring --keyring ./ubuntu-archive-keyring.gpg -a > --default-key <mykey> --output cd/dists/yakkety/Release.gpg --detach-sig > cd/dists/yakkety/Release > cd cd; md5sum `find ! -name "md5sum.txt" ! -path "./isolinux/*" -follow -type > f` > md5sum.txt; cd .. > genisoimage -o output.iso -r -J -no-emul-boot -boot-load-size 4 > -boot-info-table -b isolinux/isolinux.bin -c isolinux/boot.cat ./cd > > The cd installation will abort with > > apt configuration problem > An attempt to configure apt to install additional packages from CD > failed. > > The debug output on vt4 show me > > gpgv: Signature made Tue .... > gpgv: using RSA key > gpgv: Can't check signature: No public key > . > . > apt-setup: W: Signature verification failed for > /media/cdrom/diss/yakkety/Release.gpg > > I verified the install ubuntu-archive-keyring.gpg on my build host with > > gpgv --keyring ./ubuntu-archive-keyring.gpg cd/dists/yakkety/Release.gpg > cd/dists/yakkety/Release ubuntu-archive-keyring.gpg file is not used by apt, on installed systems, in yakkety and up. gpgv --keyring /etc/apt/trusted.gpg.d/your-key-name.gpg cd/dists/yakkety/Release.gpg cd/dists/yakkety/Release must work, and for that you must ship /etc/apt/trusted.gpg.d/your-key-name.gpg in the ubuntu-keyring .deb package. > gpgv: Signature made Tue Oct 25 14:55:11 2016 CEST > gpgv: using RSA key > gpgv: Good signature from "Signing Key Namexx <x...@yyy.com>" > > So it looks good for me.
