No such file or directory: '/etc/apt/sources.list.d'

So... I get this error message when i get to add/remove programs:
"
Traceback (most recent call last):
  File "/usr/share/ubuntu-tweak/mainwindow.py", line 566, in setup_notebook
    page = page()
  File "/usr/share/ubuntu-tweak/sourceeditor.py", line 383, in __init__
    self.update_source_combo()
  File "/usr/share/ubuntu-tweak/sourceeditor.py", line 429, in update_source_combo
    for file in os.listdir(SOURCE_LIST_D):
OSError: [Errno 2] No such file or directory: '/etc/apt/sources.list.d'
"

It's probably related to https://bugs.launchpad.net/ubuntu-tweak/+bug/337251

It's easily fixed by creating the folder using:
sudo mkdir /etc/apt/sources.list.d
