PackageKit logs a message about "only_trusted:0"

I ran pkcon update force. I noticed PackageKit is logging about only_trusted:0. That is, an operation where the only_trusted option is disabled. Even though I did not pass --allow-untrusted to pkcon. PackageKit: uid 1000 is trying to obtain org.freedesktop.packagekit.system-sources-refresh auth (only_trusted:0) So PackageKit is writing a log message about allowing untrusted packages. I did not want it to do that. I did not ask it do that. Why is it logging this message? Is there a problem in PackageKit? $ sudo systemctl status packagekit.service ● packagekit.service - PackageKit Daemon Loaded: loaded (/usr/lib/systemd/system/packagekit.service; static; vendor preset: disabled) Active: active (running) since Mon 2019-04-08 12:34:58 BST; 1min 29s ago Main PID: 19819 (packagekitd) Tasks: 3 (limit: 4915) Memory: 192.7M CGroup: /system.slice/packagekit.service └─19819 /usr/libexec/packagekitd Apr 08 12:34:58 alan-laptop PackageKit: daemon start Apr 08 12:34:58 alan-laptop systemd: Starting PackageKit Daemon...
