Update from 5.10 to 6.06 isn't working - initscripts

[Michael Salbeck]

Hello,

after the start of the Update from 5.10 to 6.06, there is an problem 
whit the paket "initscripts (2.86.ds1-6ubuntu32)":

Error: mkdir: Can't create folder /.root/var : the file exists

I have rebooted (because of "folder in use") -> folder deleted -> next 
try -> same error

Every time the initscripts paket creates the folder and stops with the 
error and the Update ist broken (half 5.10, half 6.06).
What now?

Thanks for any help

Michael
