For the last two years, I have not been able to do handle any changes, update or install new software as there is a major issue with the Synaptic Package Manager and also a similar situation occurs are the terminal level.
I cannot even update nor upgrade Ubuntu. Everything seems to be blocked by the following errors:
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/www.iri.upc.edu_cuik_ubuntu_dists_xenial_main_binary-amd64_Packages
E: The package lists or status file could not be parsed or opened.
E: _cache->open() failed, please report.
