And now I have a log where the update process reproducible fails on Sources.bz2 files (and only such, no others seem to be affected). That is exactly what I have seen on Ubuntu a while ago, randomly appearing and disappearing. You see there that something is seriously broken in apt's control flow. First it try to decompress something non-existent (empty files?). But, despite of shocking error message, the files are in fact silently fetched/unpacked and the contents is correct. What is going on? I also noticed that after such a breakage there is some junk left in /var/lib/apt/lists/partial/. Reruning updates removes the garbage and there are no errors anymore. But when I remove the garbage manually, apt also produces failed bzip2 runs. Sorry, WTF? zombie:/tmp# apt-get update Get:1 http://ftp.uni-kl.de unstable Release.gpg [189B] Get:2 http://ftp.uni-kl.de experimental Release.gpg [189B] Get:3 http://ftp.uni-kl.de stable Release.gpg [189B] Ign http://ftp.uni-kl.de unstable Release.gpg Hit http://ftp.uni-kl.de unstable Release Hit http://ftp.uni-kl.de experimental Release Hit http://ftp.uni-kl.de stable Release Ign http://ftp.uni-kl.de unstable Release Hit http://ftp.uni-kl.de unstable/main Packages/DiffIndex Hit http://ftp.uni-kl.de unstable/contrib Packages/DiffIndex Hit http://ftp.uni-kl.de unstable/non-free Packages/DiffIndex Get:4 http://ftp.uni-kl.de unstable/main Sources/DiffIndex [12.5kB] Get:5 http://ftp.uni-kl.de unstable/contrib Sources/DiffIndex [12.5kB] Get:6 http://ftp.uni-kl.de unstable/non-free Sources/DiffIndex [12.5kB] Get:7 http://ftp.uni-kl.de unstable/main Sources/DiffIndex [12.5kB] Get:8 http://ftp.uni-kl.de unstable/contrib Sources/DiffIndex [12.5kB] Get:9 http://ftp.uni-kl.de unstable/non-free Sources/DiffIndex [12.5kB] Hit http://ftp.uni-kl.de experimental/main Packages/DiffIndex Get:10 http://ftp.uni-kl.de experimental/main Sources/DiffIndex [12.5kB] Ign http://ftp.uni-kl.de stable/main Sources/DiffIndex Ign http://ftp.uni-kl.de stable/contrib Sources/DiffIndex Ign http://ftp.uni-kl.de stable/non-free Sources/DiffIndex Ign http://ftp.uni-kl.de unstable/main Packages/DiffIndex Ign http://ftp.uni-kl.de unstable/unikl Packages/DiffIndex Ign http://ftp.uni-kl.de stable/main Sources Ign http://ftp.uni-kl.de stable/contrib Sources Ign http://ftp.uni-kl.de stable/non-free Sources Ign http://ftp.uni-kl.de unstable/main Packages Ign http://ftp.uni-kl.de unstable/unikl Packages Hit http://ftp.uni-kl.de stable/main Sources Hit http://ftp.uni-kl.de stable/contrib Sources Hit http://ftp.uni-kl.de stable/non-free Sources Hit http://ftp.uni-kl.de unstable/main Packages Hit http://ftp.uni-kl.de unstable/unikl Packages Fetched 88.1kB in 2s (33.2kB/s) Reading package lists...
