Update to 16.04: Window to large to reach buttons

[Jonathan]

In the update process (the one that's automatically triggered), the window where it informs you what packages are removed and so on, the window is fixed to a to large size.

Had to rotate the screen to reach button, still couldn't make the window smaller.
