Each and every time that I run update, the last 4 lines read as follows:
Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/extras.ubuntu.com_ubuntu_dists_trusty_main_i18n_Translation-en%5fCA
E: The package lists or status file could not be parsed or opened.
What can or must I do to resolve this problem?
