The version I get by typing sudo apt-get install kdeconnect (or kdeconnect-plasma) looks like it's older than the version I see people using in youtube videos. It is conspicuously missing the most of the plugins, including the one I need "clipboard". I can't see from the community wiki or the github page how one is supposed to find or install plugins either.

Are there up to data binaries somewhere or am I going to have to try and build it from source? OR have I got the correct version and am just ignorant of how plugins are found and installed?

A tad more information about your distribution and Plasma version could be useful here...
