Fresh install as noted in report.
Software & Settings will not run. Throws Apport errow when clicked, thus preventing me from completely updating settings and setup after new install.

I would say something happened in the install.
Before I forget, not a major issue; but the slide show panels display 13.10 instead of 14.x during the install which could confuse someone when installing Trusty.

[Ubuntu Foundations Team Bug Bot (crichton)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. It seems that there was an error on your system when trying to install a particular package. Please execute the following command, as it will clear your package cache, in a terminal:

sudo apt-get clean

Then try performing the update again. This will likely resolve your issue, but the failure could be caused by filesystem or memory corruption. So please also run a fsck on your filesystem(s) and a memory test. Thanks in advance!
