I am brand new to linux, so pardon the ignorance. I recently installed Linux Mint 15 KDE edition, and i'm trying to install qtcreator. From what little i know of linux, i am to obtain software packages from a repository. In mint, i have the Software Manager application open, and when i search qtcreator or any combination of qt, nothing comes up. I also noticed that there is only 2000+ applications available. Did mint not set my software sources entirely? if not, what repositories should i be looking for. I was also looking for chromium, and that didn't exist either. I desperately want to stop using windows, but not being able to find programs along with some other issues, is making it very difficult for me.
EDIT: @Chris, i ran the update command and i got a TON of errors. Here is the output.

i have not installed or done anything at all to this fresh install of Mint with KDE. Is this something people always deal with right off the bat with linux?
apt-get update
. Now there should be moresudo rm /var/lib/apt/lists/* -fv
than runsudo apt-get update
.
