Yup, install-local does indeed trigger package-install not package-
install-untrusted

Title:
Packagekit lets user install untrusted local packages in Bionic and
Focal
Status in packagekit package in Ubuntu:
Triaged
Bug description:
We have packagekit configured to allow users to install trusted
packages from preconfigured repositories, but disallowed them to
install any untrusted packages.
The policykit configuration we use is following:
[tld.univ.packagekit]
Identity=unix-group:adm;
Action=org.freedesktop.packagekit.package-install;org.freedesktop.packagekit.package-reinstall;org.freedesktop.packagekit.package-remove;org.freedesktop.packagekit.system-sources-refresh;org.freedesktop.packagekit.system-update;org.freedesktop.packagekit.repair-system;
ResultAny=auth_self
ResultActive=auth_self
ResultInactive=auth_self
[tld.univ.packagekit-deny]
Identity=unix-user:*;
Action=org.freedesktop.packagekit.package-install-untrusted;
ResultAny=no
We would expect this to prevent users from installing local packages
downloaded from random repositories, however this does not seem to be
the case.
pkcon install-local random_package.deb will happily prompt for the
user to authenticate and will install the package, while pkcon
--allow-untrusted install-local random_package.deb will prompt for
root password, which the user does not have.
Our initial toughts was that the issue would be in packagekitd, but
after further investigations it looks like the issue could be in aptcc
backend.
We are more than happy to provide you with further details, but the
above should be enough to reproduce the issue.
