[Bug 1599051] Re: package shim-signed 1.16~14.04.1+0.8-0ubuntu2 failed to install/upgrade: subprocess installed post-installation script was killed by signal (Terminated)

[Mathieu Trudel-Lapierre]

I filed https://bugs.launchpad.net/ubuntu/+source/aptdaemon/+bug/1599981
to track the issues we've found in aptdaemon which appear to be causing
this.

We'll workaround this issue by prompting for the password in clear text.
I'm finishing up testing this alternative now. It appears to be the
least bad option given that update-manager and aptdaemon run without
root privileges, which would be necessary for access to the debconf
password database. This would also explain why you can't run into this
particular issue if update-manager is run with sudo.
