I am using Ubuntu 14.04(with Unity). Just today(as of the date of this post) I did a sudo apt-get update && sudo apt-get upgrade and at the end of the 'Upgrade' process I got the following error :-

Setting up crossplatformui (1.0.38) ...

dpkg: error processing package crossplatformui (--configure):

E: Sub-process /usr/bin/dpkg returned an error code (1)

From then on whatever apt-get command I use(so far as I know, except apt-get update) I keep getting the above error at the end of the process. But whichever apt-get command I use does what it has to without fail.(For example I tried installing blender with sudo apt-get install blender and it installed fine though it showed the above error.) After this I even got a kernel update(from 3.13.0-27 to 3.13.0-29 via the Software Updater), but even now the issue persists. How do I solve this issue?
