Adding FIPS at end of autoinstall, how to do this correctly

We have a landscape server here from which we obtain FIPS code and updates. I want to add all of this during the autoinstall, in the late-commands section. But, I seem to be triggering something as this causes the installation to go interactive. Here's the relevant section:

- ['curtin', 'in-target', '--target=/target', '--', 'bash', '-c', 'echo "deb http://dmz-landscape.domain.com/repository/standalone/esm focal-infra-updates main" >> /etc/apt/sources.list']
- ['curtin', 'in-target', '--target=/target', '--', 'bash', '-c', 'echo "deb http://dmz-landscape.domain.com/repository/standalone/esm focal-infra-security main" >> /etc/apt/sources.list']
- ['curtin', 'in-target', '--target=/target', '--', 'bash', '-c', 'echo "deb http://dmz-landscape.domain.com/repository/standalone/fips-updates focal-updates main" >> /etc/apt/sources.list']
- ['curtin', 'in-target', '--target=/target', '--', 'wget', '-O', '/etc/apt/trusted.gpg.d/our-landscape-cert.gpg', 'http://server.domain.com/media/our-landscape-cert.asc.gpg']
- ['curtin', 'in-target', '--target=/target', '--', 'bash', '-c', 'echo '\''Dir::Etc::trustedparts "/etc/apt/trusted.gpg.d/";'\'' > /etc/apt/apt.conf.d/51trustedparts']
- ['curtin', 'in-target', '--target=/target', '--', 'apt-get', 'update']
- ['curtin', 'in-target', '--target=/target', '--', 'apt-get', 'install', '-y', 'linux-tools-fips', 'ubuntu-fips']

I have tried multiple variations using quotes around the Dir::Etc::trustedparts to no avail; this part seeming necessary to get the apt process to trust the key. The key I'm importing is de-armored.

I removed those latter steps after importing the key and the autoinstall works.

Any feedback on how to fix this would be appreciated.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
