Aptitude error: The package index files are corrupted.

[Fan Liu <fan.d.liu@gmail.com>]

Hi all, 

I encountered such an error when I try to upgrade my debian lenny.

Writing extended state information... Error!
E: The package index files are corrupted. No Filename: field for package libdb4.5.

As Ken Caldweel suggested, I checked the file /var/lib/dpkg/available , but
haven't found any entry started with 'Filename'.

Anyone know what the problem really is? Thanks a lot.
