Binary package hint: update-manager

E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/lb.archive.ubuntu.com_ubuntu_dists_jaunty-updates_restricted_binary-i386_Packages
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.

When getting the log file I got the following details:

Thanks for your report.

This was some time ago, but if it's still an issue, remove the file /var/lib/apt/lists/lb.archive.ubuntu.com_ubuntu_dists_jaunty-updates_restricted_binary-i386_Packages and run
$ sudo apt-get update

This will likely fix your issue. If so, then set the status of this report to 'Invalid'. Thanks.
