Ubuntu :: DPKG Interrupted - How To Remove Unneeded Installs

I attempted to install gnucash just now to test it out, but, in the middle of the installation (which I was doing through Terminal), something happened and dpkg was interrupted. I'm unable to provide the Terminal output because (a) for some reason, prior to the error messages about a segment fault, the terminal shows a number of blank lines and does not show me what happened before the segfault, and (b) after the segfault, when I tried starting up gedit or make a screen capture, the prompt windows were blank, so I was unable to save the terminal output to either.

When I restarted Ubuntu, it told me that /tmp was not ready; I waited for it to mount, and, apparently, it did, as Ubuntu restarted fine. I tried updating my software, as the icon in my panel was telling me I needed updates. However, it told me that dpkg had been interrupted and that I needed to troubleshoot it with sudo apt-get install -f, which then told me to run sudo dpkg --configure -a, which I did, receiving the following output:

Code:
sqlu@thalamus:~$ sudo apt-get install -f

E: dpkg was interrupted, you must manually run 'sudo dpkg --configure -a' to correct the problem.
sqlu@thalamus:~$ sudo dpkg --configure -a

It looks like there were errors with a number of packages, and I'm guessing something else might have also broken. Since I'm already using homebank and don't really need to use gnucash, I was wondering if there was a way for me to check what was installed by gnucash and remove those packages, since they're cluttering my system, and I'm concerned that they might interfere with other packages if they're broken or something. I've been using Ubuntu for about two years now and have some knowledge of the command line and such, but I'd say my skills are still pretty basic. I'm running 64-bit 10.04.
