Package: apper Version: 1.0.0 I think the installation history of the GUI Apper is very useful: it shows a history of package installs and removals with timestamps. I think it should also show other installations made via the command-line (dpkg.log files and .deb file installs). I don't know of any other pre-installed GUI in KDE that also shows an installation log and I proposed that non-default KSystemLog includes it.
It doesn't show any entries anymore under History which are still shown on another machine. I recently upgraded from Debian11 to 12. When running apper in the console and opening the History page, it shows: >QObject::connect: No such slot >PackageKit::Transaction::transaction(QDBusObjectPath,QString,bool,uint,uint,QString,uint,QString). Before opening the page there is: >QCommandLineParser: already having an option named "h" >QCommandLineParser: already having an option named "help-all" >QCommandLineParser: already having an option named "v" >QCommandLineParser: option not defined: "install-provide-file" >apper: >apper:
