unable to open synaptic package manager

[nuke_fluke]

I am unable to open synaptic package manager....
It gives the following error message

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



So when I type the above command in terminal,
i get this

dpkg: requested operation requires superuser privilege

What do I do now?
I am not able to remove or install any software...

Try typing " sudo dpkg --configure -a "

thanks ...it worked

I am now able to open the synaptic..

But the following message came in terminal:

Setting up gcc-3.3-doc (1:3.3.6-15ubuntu4) ...
sh: cannot open /usr/share/info/gcc-3.3.info.gz: No such file
install-info(/usr/share/info/gcc-3.3.info.gz):
dpkg: error processing gcc-3.3-doc (--configure):

Setting up gcc-3.4-doc (3.4.6-6ubuntu3) ...

Errors were encountered while processing:
gcc-3.3-doc
gcc-3.4-doc

Can you tell me what that means?

Before that let me tell you that the GCC I installed did not install properly as I have tried to run the simplest of C programs and it says
stdio.h does not exist...

How can I reinstall the whole GCC from scratch...

Thanks..

Thank you SO MUCH for the " sudo" at the start of the session.

Forgive my ignorance, but what does that command do that enables you to login as a superuser on Konsole?
