how to fix a broken package
 

I got a broken package problem when try to install some package and update my OS(ubuntu). the error message as follow:

E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/ppa.launchpad.net_antonio.chiurazzi_ppa_ubuntu_dists_precise_main_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.

what should i do?

Welcome to LQ.

Remove the "ppa.launchpad.net_antonio.chiurazzi_ppa" entry
in Synaptic ( if available ), or in /etc/apt/sources.list :

gedit /etc/apt/sources.list
... and then delete the "antonio.chiurazzi_ppa" line(s).

And afterwards refresh the package lists : sudo apt-get update

.

I've try to edit the "souuce.list" but i did not find "antonio.chiurazzi_ppa"

Can you post your source.list here.

OK, the "ppa" text is probably in :

/etc/apt/sources.list.d/<name>.list

thank you. finally i can fix my ubuntu
