I checked the patch again on bionic, turns out I missed the packagekit restart the first time and the package postinst script for one reason or another didn't restart the daemon on my test machine as it did on focal. The patch seems to work on bionic as well.

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.
