# ifup -a
ifup: failed to open statefile /run/network/ifstate: No such file or
directory
I misread at first - but "ifup a" produces the same result.

Yes - and have restarted several times now. :-(
"ifconfig -a" shows eth0 and lo, neither of which has an IP.
I have checked hardware with a live CD, since it is not beyond the
bounds of possibility that the card could break coincidentally with
my finishing the upgrade. But, not only is it fine, but the results
above suggest software not hardware.
I am now googling on the error mesage; but all help most welcome!
