I have v 12.04 installed. When I am running update manager the following error message is appearing:
Could not initialize the package information
An unresolvable problem occurred while initializing the package information.
Please report this bug against the 'update-manager' package and include the following error message:
'E:Encountered a section with no Package: header, Eroblem with MergeList /var/lib/apt/lists/security.ubuntu.com_ubuntu_dists_precise-security_universe_binary-i386_Packages, E:The package lists or status file could not be parsed or opened.'
Could anyone please suggest the solution.
