Ubuntu Installation :: DPKG - Error Processing Some Upgrades

I am running Lucid 32-bit server P3 command line server version that began life as a 9.10-server, now upgraded to 10.04. Upgrade has been running since June, 2010. A few weeks ago, I realized that phpldapadmin was not running correctly. In finding the solution for the phpldapadmin issue, now, upgrades are giving me the following:

Code:
admin@myserver:/$ sudo apt-get update[sudo] password for administrator:
Hit [URL]
Get:1 [URL]
Ign [URL]
Ign [URL]

>>>> snip <<<<<
Reading package lists... Done
administrator@wdnserver:/$ sudo apt-get upgrade .....
No apport report written because MaxReports is reached already

Errors were encountered While processing:
grub-pc
samba-common
samba-common-bin
smbclient
smbfs
E: Sub-process /usr/bin/dpkg returned an error code (1)

I have read many posts trying to find a reference to
Code:
dpkg: error processing grub-pc (--configure):
subprocess installed post-installation script returned error exit status 10
because this started with grub-pc being the first and only package that refused to install. I have yet to find a direct reference to 'error exit status 10'. I find many other status codes, but few of 'status 10'.

Now, unfortunately, work took me away for a few of weeks and now I am getting errors for:
grub-pc
samba-common
samba-common-bin
smbclient
smbfs

I have tried
Code:
apt-get -f install
and that does work.

I have tried
Code:
apt-get purge grub-pc
and then re-installing grub-pc still gives same error.

And finally there are many other attempts, all with the same result.
