Hello Seth, I can now confirm that it does not matter if the test users are in no groups.
The issue persists. Lines 49 to 56 in the link I provided earlier describe the package- install-untrusted action which should be triggered when installing local packages: <action id="org.freedesktop.packagekit.package-install-untrusted"> <!-- SECURITY: - Normal users require admin authentication to install untrusted or unrecognised packages, as allowing users to do this without a password would be a massive security hole. - This is not retained as each package should be authenticated. --> <description>Install untrusted local file</description> AFAIK this works as intended with other than aptcc backends, eg in Red Hat. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to the bug report. https://bugs.launchpad.net/bugs/1882098 Title: Packagekit lets user install untrusted local packages in Bionic and Focal To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/packagekit/+bug/1882098/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
