I am a bit of a noob with Linux. Several months ago I updated to Ubuntu 12.04, then stopped using Ubuntu for a while for a variety of reasons. Now I would like to go back to it, but I have a couple of problems. For one thing, the Software Center will simply not load. I click on the icon, the program comes up, but it never loads, and when I close it I get a "window not responding" message. While reading some threads to fix this issue, the common theme was that the main solution was to update by running:

sudo apt-get install --reinstall software-center

However, when I run that, I get the following (long):

bcoleary@ubuntu:~$ sudo apt-get install --reinstall software-center [sudo] password for bcoleary: Reading package lists... Done Building dependency tree
Reading state information... Done You might want to run 'apt-get -f install' to correct these: The following packages have unmet dependencies: kdelibs-bin : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed Depends: libkjsapi4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed kdelibs5-plugins : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 >is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed Depends: libkjsapi4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 >is to be installed Depends: libkntlm4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed kdoctools : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed libkcmutils4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed libkde3support4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed Depends: libkpty4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed libkdeclarative5 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 >is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed libkdewebkit5 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed libkdnssd4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be >installed libkemoticons4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed libkfile4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be >installed libkhtml5 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be >installed Depends: libkjsapi4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be >installed libkidletime4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed libkio5 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be >installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be >installed libkjsembed4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed Depends: libkjsapi4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to >be installed libkmediaplayer4 : Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed libknewstuff3-4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 >is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is >to be installed libknotifyconfig4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 >is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 >is to be installed libkparts4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libkrosscore4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libktexteditor4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libnepomuk4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libnepomukquery4a : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libnepomukutils4 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed libplasma3 : Depends: libkdecore5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libkdeui5 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed Depends: libthreadweaver4 (= 4:4.8.3-0ubuntu0.1) but 4:4.8.5-0ubuntu0.1 is to be installed E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

So the next thing I tried was:

sudo apt-get -f install

The following has been cut down, but you get the idea:

                                                              Errors were encountered while processing:

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

Basically it said a ton of stuff was missing. Maybe this happened when I upgraded, I am not sure.

Is there a way to fix this? And if not what is the best way to un-install and re-install Ubuntu? It is currently dual-booted with Windows 7. If you need anymore info, please let me know. Thank you for helping a beginner! :)
