I looked around I can't find anything to help me solve this problem I have with apt-get.

When I try to install a package, let's just use wine as an example I get this:
jts@jts-laptop:~$ sudo apt-get install wine
Reading package lists... Done
Building dependency tree
Reading state information... Done
The following packages were automatically installed and are no longer required:
jikes libsablevm-native1 jikes-sablevm libsablevm-classlib1-java
Use 'apt-get autoremove' to remove them.
Suggested packages:
msttcorefonts xdg-utils
The following NEW packages will be installed:
wine
0 upgraded, 1 newly installed, 0 to remove and 0 not upgraded.

So then I obviously try to update and get this:
