Ok so do this:
1. Open a terminal by hitting CTRL + ALT + T
2. Run this command for edit the file:
sudo gedit /etc/apt/sources.list

3. Now, in the Text Editor, you have to remove ONLY the bottom line of the file, exactly this:
usage: sudo -h | -K | -k | -L | -V
usage: sudo -v [-AknS] [-p prompt]
usage: sudo -l[l] [-AknS] [-g groupname|#gid] [-p prompt] [-U username] [-u
username|#uid] [-g groupname|#gid] [command]
usage: sudo [-AbEHknPS] [-C fd] [-g groupname|#gid] [-p prompt] [-u
username|#uid] [-g groupname|#gid] [VAR=value] [-i|-s] [<command>]
usage: sudo -e [-AknS] [-C fd] [-g groupname|#gid] [-p prompt] [-u
username|#uid] file ...

So select this lines and remove it from the file. Then save.

After you have saved, in the terminal run:
sudo apt-get update

Try to open now the Ubuntu Software Center
