I was having some serious network troubles, and now running
sudo apt-get update gives this error:
... Hit ftp://ftp.is.co.za experimental/contrib i386 Packages Reading package lists... Error! E: Encountered a section with no Package: header E: Problem with MergeList /var/lib/apt/lists/ftp.is.co.za_debian_dists_testing_main_binary-i386_Packages E: The package lists or status file could not be parsed or opened.
It's an odd one because I've never seen it before. Have you experienced it? How can I fix it?
