I can't believe the detail over a widget.

Having been unsuccessful at installing Lancelot through the Desktop - adding widgets. I installed Lancelot through the Debain Package Manager. It installed without a problem.

I have tried to install Desktop Themes via Systems Settings, again without success. I am wondering if these can also be installed by another method

Plasmoids

You need to read the information what the GHNS is offering: The Lancelot is telling that it is part of KDE and you should install it from the distribution's package repositories...




Desktop themes

You need to tell the desktop theme name what you are trying to install.
