update manager stucks in middle of process

[hit]

my system specs:
HP Compaque Business Desktop DX6100
P4 3.0 Ghz
1024 MB RAM 2 SATA HDD , 20, 40,
Dual Boot with Win 7
Win 7 on hd0

While updating ubuntu, update manager throws error and suggest filing bug report

'E:Unable to parse package file /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_natty-updates_universe_binary-i386_Packages (1), E:The package lists or status file could not be parsed or opened.'

I tried to update many times but same thing happened again and again. Yesterday it was working fine.

Thanks...

Hi,
Thanks for reporting this bug.
Does it also tell you that "Encountered a section with no Package: header"
It could eventually be a duplicate report of the Bug #346386.
In this case you could find an answer to your specific problem here:
http://ubuntuforums.org/showthread.php?t=1750755&highlight=Encountered+section+Package%3A+header

Otherwise please give log information about your system by typing on terminal:
apport-collect 804983

I had this bug and fixed it by the following.
Make sure you are authenticated before running the rm.

sudo rm /var/lib/apt/lists/* -vf
sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade

I m very thankfull to Launchpad user "xillix" for a very simple and prompt solution.

thanks a lot !

Please close this bug event.

thanks all of u for support...
