bionic 20101020ubuntu535: netboot installer fails with local repository

[Jay McCanta]

Using a preseed file with network boot 20101020ubuntu535 , the apt sources configuration is built correctly.

Preseed:
d-i apt-setup/local0/repository string deb http://example.com/PatchSet/latest/homegrown bionic main
d-i apt-setup/local0/comment string This is the homegrown-custom stuff
d-i apt-setup/local0/key string http://example.com/PatchSet/latest/homegrown/gpgkey.pub

yields a sources.list file with

deb http://example.com/PatchSet/latest/homegrown bionic main

However, after 'Configure APT', the file is modified and the correct line is commented out. The installer then fails when trying to install packages from that repository.

Only workaround that seems to work is moving the installation of the pacakges to late_command and have it configure apt sources manually.

Upon further troubleshooting. The error occurs in /usr/lib/apt-setup/generators/60local. The apt-key command has this error:

E: gnupg, gnupg2, and gnupg1 do not seem to be installed, but one of them is required for this operation.

It appears that while gpgv is installed in the base image, gnupg (or gpg) is not. In Xenial, gnupg is installed in the base image.

Further research shows that the gnupg in bionic has a Priority: optional header.
In ardvark, xenial and trusty, Priority: important.

Status changed to 'Confirmed' because the bug affects multiple users.
