I'm new to Ubuntu. I got a disk from a friend which contains release 11.04 but package manager does not work. How do I solve this?
Here is the error message:
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/us.archive.ubuntu.com_ubuntu_dists_natty_main_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.
