Unable to upgrade Ubuntu from 9.10 to 10.04

[Ben Elston]

Binary package hint: update-manager

When I ran the upgrade for 9.10 to 10.04 I encountered a problem when it hit "Installing the upgrade". The progress bar moves and says "Applying changes" but in terminal all you see is
y
y
y
y
y
etc.
I tried watching the install this time and it gets about 2 lines in before this continuous y then enter happens. I'm not 100% sure which process in process manager is responsible for "Distribution upgrade" but all processes apart from firefox and system monitor are asleep.

I tried deleting the entire cache and starting over but no matter what I do this always seems to end any attempt to upgrade. I tried to use synaptic to reinstall debconf but it was unable to saying "E: debconf: subprocess installed post-installation script returned error exit status 1"

This is what I got in terminal when I tried to upgrade that way.

Unpacking replacement debconf ...
Processing triggers for man-db ...
Setting up debconf (1.5.28ubuntu4) ...
debconf: DbDriver "config": /var/cache/debconf/config.dat is locked by another process: Resource temporarily unavailable
dpkg: error processing debconf (--configure):
 subprocess installed post-installation script returned error exit status 1

 debconf
E: Sub-process /usr/bin/dpkg returned an error code (1)

does the command
$ fuser -v /var/cache/debconf/config.dat

returns something ? If not does the following command still fails ?
$ sudo apt-get install debconf

[Monkey (monkey-libre)]

Please do in the terminal (Applications>Accesories>Terminal) the next command and copy here the output:
sudo dpkg --configure -a

Thanks in advance.

fuser -v /var/cache/debconf/config.dat never managed to return anything last night

After a restart we are back to the original problem. If I do sudo apt-get upgrade it starts loading up everything fine and then I just get a screen full of "y" Last time I left this for over 24 hours and while it did eventually dissapear I think that had more to do with timing out then actually completing anything.

I tried to run Synaptic but it couldnt get an exclusive lock, no other program like apt get seemed to be running and when I tried again it told me to run "sudo dpkg --configure -a" Which resulted in this
Setting up libselinux1 (2.0.89-4) ...

Processing triggers for libc-bin ...
ldconfig deferred processing now taking place

I was able to get into Synaptic and hit the mark allupgrade and applied it
It downloaded a whole lot of bits a pieces but in the end appears to be stuck still with the y problem in terminal. I will leave it to see if it clears itself up but I doubt it.
