apt-get updates broken? problem with MergeList?

Thesd days I've add some sources to the /ect/apt/sources.list, and found I cannot update anymore... this is what i get...

E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/dpkg/status
E: The package lists or status file could not be parsed or opened.

I've tryed to substitute status with status.old but nothing changes...

my /var/lib/dpkg/status file is as follows...

and finally found some soluation on Internet:

 

Solution 1:

 

Code:

dpkg --configure -a

Code:

apt-get -f install

if that does not work look in

Code:

/var/lib/dpkg/info

The above location stores what are called post-installation (.postinst) and post-removal (.postrm) scripts from deb packages which include them. Sometimes, packagers do not do a good job of packaging software and these scripts (which are NOT present in all debs) error out (during installation or uninstallation) and prevent apt from doing anything further (in terms of installing or uninstalling other packages).
What you need to do then is delete the faulty scripts from the above location and then apt-get remove the package.
That will fix apt.

and then manually go and repir anything else that shows up

 

Solution 2:

 

cd /var/lib/dpkg
mv status status-bad
cp status-old status
apt-get update

 

Problem continue:

 

I needed to remove the lock before I could run the update.

Code:

sudo rm -f /var/lib/dpkg/lock
