I incremented the package version to +mytest001 and added my gpg public key to /etc/apt/trusted.gpg.d/ in both packages (deb + udeb). Then i copied the resulting file into cd/pool/main/u/ubuntu-keyring/ and removed the old files. After the rebuild of the Packages and Release files and signing the Release file and the problem still occurs: apt configuration problem An attempt to configure apt to install additional packages from CD failed There is no /etc/apt/trusted.gpg.d/ directory and therefore no file. > Can you paste contents of your ubuntu-keyring_*_all.deb? e.g. output > of $ dpkg-deb -c ubuntu-keyring_*_all.deb > Here is my contents of the .deb und .udeb package: drwxr-xr-x root/root 0 2016-10-25 21:51 ./ drwxr-xr-x root/root 0 2016-10-25 21:51 ./etc/ drwxr-xr-x root/root 0 2016-10-25 21:51 ./etc/apt/ drwxr-xr-x root/root 0 2016-10-25 21:51 ./etc/apt/trusted.gpg.d/ -rw-r--r-- root/root 1201 2016-10-25 21:51 ./etc/apt/trusted.gpg.d/mytest-keyring-2016-test.gpg -rw-r--r-- root/root 3422 2016-10-25 21:51 ./etc/apt/trusted.gpg.d/ubuntu-keyring-2004-archive.gpg -rw-r--r-- root/root 3147 2016-10-25 21:51 ./etc/apt/trusted.gpg.d/ubuntu-keyring-2004-cdimage.gpg -rw-r--r-- root/root 2796 2016-10-25 21:51 ./etc/apt/trusted.gpg.d/ubuntu-keyring-2012-archive.gpg -rw-r--r-- root/root 2794 2016-10-25 21:51 ./etc/apt/trusted.gpg.d/ubuntu-keyring-2012-cdimage.gpg drwxr-xr-x root/root 0 2016-10-25 21:51 ./usr/ drwxr-xr-x root/root 0 2016-10-25 21:51 ./usr/share/ drwxr-xr-x root/root 0 2016-10-25 21:51 ./usr/share/doc/ drwxr-xr-x root/root 0 2016-10-25 21:51 ./usr/share/doc/ubuntu-keyring/ -rw-r--r-- root/root 157 2016-10-25 21:51 ./usr/share/doc/ubuntu-keyring/README.gz -rw-r--r-- root/root 2163 2016-10-25 21:51 ./usr/share/doc/ubuntu-keyring/changelog.gz -rw-r--r-- root/root 1242 2016-10-25 21:51 ./usr/share/doc/ubuntu-keyring/copyright drwxr-xr-x root/root 0 2016-10-25 21:51 ./usr/share/keyrings/ -rw-r--r-- root/root 13360 2016-10-25 21:51 ./usr/share/keyrings/ubuntu-archive-keyring.gpg -rw-r--r-- root/root 0 2016-10-25 21:51 ./usr/share/keyrings/ubuntu-archive-removed-keys.gpg -rw-r--r-- root/root 1227 2016-10-25 21:51 ./usr/share/keyrings/ubuntu-master-keyring.gpg and drwxr-xr-x root/root 0 2016-10-25 21:51 ./ drwxr-xr-x root/root 0 2016-10-25 21:51 ./etc/ drwxr-xr-x root/root 0 2016-10-25 21:51 ./etc/apt/ drwxr-xr-x root/root 0 2016-10-25 21:51 ./etc/apt/trusted.gpg.d/ -rw-r--r-- root/root 1201 2016-10-25 21:51 ./etc/apt/trusted.gpg.d/mytest-keyring-2016-test.gpg drwxr-xr-x root/root 0 2016-10-25 21:51 ./usr/ drwxr-xr-x root/root 0 2016-10-25 21:51 ./usr/share/ drwxr-xr-x root/root 0 2016-10-25 21:51 ./usr/share/keyrings/ -rw-r--r-- root/root 13360 2016-10-25 21:51 ./usr/share/keyrings/ubuntu-archive-keyring.gpg > > > > 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.
