Well I found a folder in /opt from which I don't know the origin.

When I do ls -la /opt it gives me

marten@marten-desktop:~$ ls -la /opt/

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.

  • Well I think it's like Google Chrome or Spotify which also install in `/opt`. So do you know from which package it is? Because I want to `apt-get` remove it. – Marton Sep 13 '15 at 07:21

  • Okay thank you but Spotify and Google Chrome do install to `/opt`. Spotify has a ppa and Google Chrome is a Debian Package so why do they install to `/opt`? – Marton Sep 13 '15 at 17:11
  • Both are 3rd party applications. 3rd party applications go to /opt/. Regardless on how you install it (aptana, jasperserver and many many more install into /opt/). BTW: if you install it with a PPA and it is installed in /opt (and that install was not with a separate installations ;) ) removing software from /opt/ is always possible with `rm /opt/{software}`: that is the intention of opt: -all- parts of the software go there. – Rinzwind Sep 13 '15 at 17:17
  • What if the click package has a `/usr/bin` file, this has to removed too I guess ? – George Udosen Jan 03 '17 at 23:59
  • I did not install `clickpkg` or any kind of task app, yet still there is this (empty) directory in `/opt`. – kleinfreund Nov 15 '17 at 11:55
