apt-clone crashed with , E in update()

[Sylvestra]

Binary package hint: apt-clone

I was installing Ubuntu 11.04 beta on my Asus1201T Netbook and it went well and finished even after the crash. I kept my old /home partition and I didn't format my old / as well. This is the only difference from an install as usual I can think of...
