The Error message is :

Problem Solving : if i uninstall pencil application, it will be installed.

I wonder that, how can I make latest package to installable .deb file on xubuntu? i am a little bit new for xubuntu and unix,linux things.

as a result of the problem, we need to change application name like evoluspencil to install without any confusion for the system.
