Encountered a section with no Package: header
Follow @ggarronToday, while updating my Debian Squeeze, after running
sudo aptitude update
I got this:
E: Encountered a section with no Package: header E: Problem with MergeList /var/lib/apt/lists/ftp.debian.org_debian_dists_squeeze _contrib_binary-i386_Packages E: The package lists or status file could not be parsed or opened. E: Encountered a section with no Package: header E: Problem with MergeList /var/lib/apt/lists/ftp.debian.org_debian_dists_squeeze _contrib_binary-i386_Packages E: The package lists or status file could not be parsed or opened.
After googling a little, I found this solution.
sudo rm /var/lib/apt/lists/* -vf
This removed all the corrupted files, and the process could start again with no problems.
After that all was working again.
