'dpkg --configure -a' problem when trying to run Synaptic

"When I try to install something or update I get this error message:

E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E: _cache->open() failed, please report.

To correct this problem just open Terminal (Applications → Accessories → Terminal) and type:
sudo dpkg --configure -a

Give your user password when requested. You will not see anything, but type it and press enter.

Then retry to update and/or to install desired package."

THIS SOLUTION DOESNT WORK FOR ME !!

The listed solution leads me to
 ubuntu@ubuntu:~$ sudo dpkg --configure -a dpkg: parse error, in file `/var/lib/dpkg/updates/0056' near line 1: newline in field name `#padding'

See if you can correct the file with a text editor:

gksudo gedit /var/lib/dpkg/updates/0056

To be honest, I'd move or rename the broken file and then try:
sudo dpkg --configure -a
sudo apt-get -f install
sudo apt-get autoclean
sudo apt-get autoremove
sudo apt-get update
sudo apt-get upgrade

You have to correct the line 1 of the file /var/lib/dpkg/updates/0056 so please give us the contents of the first rows of this file as Bhavani already has asked you.

Thank you

Sorry I am new to linux and I dont know what you mean by "You have to correct the line 1 of the file /var/lib/dpkg/updates/0056 so please give us the contents of the first rows of this file "

So pleasse explain step by step.

Thank you

Open a Terminal from the menu Applications → Accessories → Terminal and type:
(if the system ask you a password give your user password, you will not see nothing when you type it, then press enter)

gedit /var/lib/dpkg/updates/0056

copy and paste here the first 3 rows of that file.

Thank you

Oh I think ....we cant install anything in live linux -- isn't it so?
btw my system is not booting up - after intel screen BOOT FAILURE press any key to continue...
Thats why I m using live cd to browse internet.

Thank you
