Status changed to 'Confirmed' because the bug affects multiple users.

I had to remove the existing unity-singlet install by `sudo dpkg --remove unity-singlet`. Only then apt-get became useful.

Same error in English:

Where did you guys get a binary package named 'unity-singlet'? It was changed to 'python-unity-singlet' before being accepted into Universe for Precise.

`sudo dpkg --remove unity-singlet` solved it for me too, it looks like it came with unity-dictionary-lens at some point.
