distribution update crashed

[Kai Thoma]

when doing a distibution update from maveric to oneiric it crashed at 88%.
Error-Messagebox told me to report this bug using "ubuntu-bug update-manager".
It also told me to attach 2 files whose name i cannot remember. Sorry :S
if you tell me which files you need i'll provide it to you.
In general update seems to have worked out but:
-Viurtual Box is working no more
-I had to configure manual IP address again (it was set to DHCP from update but my router has DHCP switched off)

This are the last lines of main.log:
