[Bug 1792497] Re: package shim (not installed) failed to install/upgrade: subprocess dpkg-deb --control returned error exit status 2

[Kevin O'Grman]

Hi, we encountered this error during installations of the SecureDrop
application, which uses Ubuntu 14.0.4.5 for its server-side OS. We put
out an advisory which you can find here: https://securedrop.org/news
/advisory-server-installation-failure-uefi-boot-mode/ -but basically
we're seeing the same error as described above.

I just tried an install using the new shim-signed package as follows:
1) installed Ubuntu 14.04.5 to servers
2) updated /etc/apt/sources.list to include the trusty-proposed repository
3) ran sudo apt-get update

Then I proceeded with the SecureDrop install, which failed at the same
task and with the same error as before:

---
fatal: [app]: FAILED! => {"cache_update_time": 1540315459, "cache_updated": false, "changed": false, "msg": "'/usr/bin/apt-get -y -o \"Dpkg::Options::=--force-confdef\" -o \"Dpkg::Options::=--force-confold\"     install 'securedrop-keyring'' failed: E: Unmet dependencies.

This is Ansible output - the actual apt-get command that failed is:

   apt-get -y -o "Dpkg::Options::=--force-confdef" -o "Dpkg::Options
::=--force-confold" install 'securedrop-keyring'

I also tried installing shim-signed directly on the server with the command:
   sudo apt-get install shinm-signed/trusty-proposed

This failed with a similar error about the shim package being an unmet
dependency.

Unless I'm setting up the -proposed repo incorrectly, I don't believe
adding dpkg as a predependency fixes this bug.
