apt show partitionmanager

Depends: libc6 (>= 2.14), libkf5configcore5, libkf5configgui5, libkf5configwidgets5, libkf5coreaddons5, libkf5crash5, libkf5i18n5, li
bkf5iconthemes5, libkf5jobwidgets5, libkf5kiocore5, libkf5kiowidgets5, libkf5widgetsaddons5, libkf5xmlgui5, libkpmcore7, libqt5core5a
(>= 5.11.1+dfsg), libqt5gui5 (>= 5.11.1+dfsg), libqt5widgets5 (>= 5.11.1+dfsg), libstdc++6 (>= 5)

However, the command apt install -s partitionmanager shows only libkpmcore7 and partitionmanager, since I have a few other programs installed on my system already.

Additionally, if you check each dependency with apt-cache rdepends librarynamehere, most of them (if not all of them) are used by many essential KDE applications.

I have 24 programs installed, KDE Neon has 14 programs by default.
