It is software you installed yourself (/opt/ is purely used for 3rd party applications you install yourself from mostly pre-compiled archives (tar.gz or something similar) and not from USC or a debian install file (if software did automatically get installed there from Ubuntu Software Center or even a debian installer (.DEB). The FileSystem Hierarchy we use has a strict rule on using /opt/)).
What you installed is probably clickpkg as part of their Ubuntu tasks app set (Ubuntu Tasks is a task management app written for Ubuntu Touch as part of the Ubuntu App Showdown.).
/opt/ is not used by "apt-get". If you want to get rid of it all you need to do to issudo rm -rf /opt/clickpkg. All software related to it -must- be in that directory when using /opt/ as an installation location.
/opt. So do you know from which package it is? Because I want toapt-getremove it. – Marton Sep 13 '15 at 07:21sudo rm -rf /opt/clickpkg.

Spotify has a ppa and Google Chrome is a Debian Package so why do they install to/opt? – Marton Sep 13 '15 at 17:11rm /opt/{software}: that is the intention of opt: -all- parts of the software go there. – Rinzwind Sep 13 '15 at 17:17/usr/binfile, this has to removed too I guess ? – George Udosen Jan 03 '17 at 23:59clickpkgor any kind of task app, yet still there is this (empty) directory in/opt. – kleinfreund Nov 15 '17 at 11:55
