apt-get and software installation frozen

[Ramesh_Jude_Fernando]

Hi I am trying to run the Ubuntu software installer and it continues to give error.

ramesh@ramesh-Aspire-V3-771:~$ apt-get upgrade
E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?
ramesh@ramesh-Aspire-V3-771:~$ sudo apt-get upgrad
E: Invalid operation upgrad

You might want to run 'apt-get -f install' to correct these.
The following packages have unmet dependencies:
 plasma-active : Depends: ksplash-theme-active but it is not installed
                 Recommends: plasma-widgets-active (= 1:0.5-0ubuntu1) but it is not installed
E: Unmet dependencies. Try using -f.

How do I get the ksplash*.* to be removed permanently so apt-get and software installer will work.

Thanks
