I am running Ubuntu 13.10 on a Toshiba Satellite Laptop.
I am trying to download Labyrinth mind-mapping tool. However, neither the software center nor the synaptic package manager will download anything. I can download the tar.gz but I want to install from the repositories (I've had some issues with organization with tar.gz's in the past).
There is no error message when using either. Once I click "install" (or in the case of Synaptic Package Manager "Apply") the downloading screen appears and just sits at "0 bytes of 98.4Mb" forever. I tried with other programs and all are the same. Nothing downloads. After 10 or so minutes I can cancel the download just fine with no error messages. The computer works fine while trying to download. I tried running a bunch of other programs to see if I had any CPU speed loss or freezing and I didn't. The System Load indicator doesn't show a spike in CPU usage either.
This is also not a problem with my internet speed or network because I tried downloading large video files from online (using Google Chrome) and they downloaded just fine. Ubuntu One is backing up my files instantaneously, and both my Dropbox and my Insync are working like lightning. My PING is at 64, my downloading speed is about 34Mbps, and my upload speed is at 3.3Mbps. Here are the speedtest results:

Again, it isn't giving any error messages so I don't know what else to say.
Any help correcting the problem would be awesome. I am sure there is a command I could put into the terminal to install the repository but what I would really like is to repair whatever is broken with both Software Center and Synaptic Package Manager.
Thanks so much for any help.
