So for sake of simplicity, i guess you have to do both: 1) import your key into /usr/share/keyrings/ubuntu-archive-keyring.gpg 2) ship your key as a key fragment in the /etc/apt/trusted.gpg.d/ (already done above) I guess I really should look into fixing d-i to use trusted.gpg.d just like the installed systems to avoid all the confusing. Because it really is a nightmare now in yakkety. I'm so sorry, that I did not test / thought of ISO customizations when migrating ubuntu to the key fragments.
