I'm trying to install a Chrome update on Linux Mint "Quiana". I downloaded the .deb file; when I try to open/run/install it, GDebi Package Installer says:
Software Index is Broken
This is a major failure of your software management system. Please check for broken packages with synaptic, check the file permissions and correctness of the file '/etc/apt/sources.list' and reload the software information with: 'sudo apt-get update' and 'sudo apt-get install -f'.
So I try to run synaptic to check for broken packages. It won't start; says
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/archive.ubuntu.com_ubuntu_dists_trusty_multiverse_i18n_Translation-en
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.
