Thank you for the bug report! However Plasma 5.18.7 is no longer supported by KDE; supported versions are 5.24, and 5.26 or newer. Your distribution is responsible for providing support for older versions of KDE software. Please do one of the following: - Upgrade to a supported version and see if the issue is still relevant - Report the issue to your distribution
Discover uses Polkit to authorize actions. Whether or not that asks for a password is a matter of polkit configuration
Not really, it depends on how PackageKit is configured, not PolKit (although yes, PackageKit uses PolKit). Either way, yes, please reach out to your distro and update to a supported Plasma version.
