apt-get freezes under lenny domU on lenny dom0

I had this strange thing ... apt-get freezing when using it inside domU ... no key strokes nothing ... although the machine still runs fine ! even if i run it inside 'screen', disconnect and reconnect ... no good, i need to kill apt-get and retry with apt-get -f install and stuff.

Well, i got it solved, i was trying to fix something else , which is an error message saying:


Time went backwards


Following the instructions here:

got me going!
