Hello,

Try to do the following steps to make your system work:

1. Open your terminal
2. Delete the old list files

  sudo rm -r /var/lib/apt/lists/*

3. Update apt cache:

  sudo apt-get update

Now run Ubuntu Tweak or Software Center, tell me if it work after
these steps.

Good luck!

Oh sorry, the command should be "sudo rm -f /var/lib/apt/lists/*"

If you run the old command, make sure to run this command to keep system correctly: sudo mkdir -p /var/lib/apt/lists/partial
