Upgrade to 12.04 did not complete normally and has left a problem with package management though machine is working

The problem occurred when I used alt-tab to try and capture some text from pop up information windows during dist-upgrade from 11.10 to 12.04 . Trying to return to the upgrade window using alt-tab was problematic. As far as I can remember the last item I saw during the install was asking if I wanted to accept changes to a network config file (which I tried to capture for later review) but on trying to alt-tab back to the pop up window, to close it and continue, the screen went blank and I had no further control/input or output to the upgrade process. It had been running for about 90 minutes and was almost complete. I left it for another hour and then decided to reboot. Machine came up though I had lost my bluetooth keyboard connection (known issue which I subsequently fixed)

The only problem I appear to have now is with package management. I followed a thread to assist in identifying the problem which asked me to post results of command line output here.

This is the sequence (please note I had to use 'cntrl c' twice because nothing was happening - see lines that start with "0% [Connecting to 192.168.1.1^C")...

I was able to remove a package 'Bluez' in Synaptic but could not reinstall it
'apt-get install' in terminal allowed me to re-install the bluez package (with its dependencies)

Update manager 'check' shows progress bar but does not finish and details window is empty even when server is changed from Ireland to Main.

apt-get update in a terminal shows same error as above '0% Connecting to 192.168.1.1'

Is there anything I can do to recover package management?

many thanks
