In last week for a cause i need to install WIN7 . I did it with dual boot. Then i lost my grub. After that using tons of tutorial I bring it back. But after that I cant install any software from Ubuntu software center or terminal or synaptic package manager.
In terminal If show this error message.
I think its a problem with the package list. How can i solve it.Code:[sudo] password for junkyeard: Reading package lists... Error! W: Duplicate sources.list entry http://archive.ubuntu.com/ubuntu/ precise/restricted i386 Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_precise_restricted_binary-i386_Packages) W: Duplicate sources.list entry http://archive.ubuntu.com/ubuntu/ precise-updates/restricted i386 Packages (/var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_precise-updates_restricted_binary-i386_Packages) E: Encountered a section with no Package: header E: Problem with MergeList /var/lib/apt/lists/download.opensuse.org_repositories_home:_sarimkhan_xUbuntu%5f12.04_._en E: The package lists or status file could not be parsed or opened.
Thanks for any help.
