i have not been able to update the system using
sudo apt-get update
sudo apt-get dist-upgrade
i have been hitting the same issue for the last 4 days or so
Reading package lists... Error!
E: Encountered a section with no Package: header
E: Problem with MergeList /var/lib/apt/lists/ftp.debian.org_debian_dists_testing_contrib_i18n_Translation-en%5fUS
E: The package lists or status file could not be parsed or opened.
while i have waited for debian to sort it out, the fact i still get the same issue after 4-5 days, makes me wonder if i need to tweak something else as well
