After reading apt-cacher source code, I sent SIGUSR1 to the daemon and saw the following snippet in apt-cacher/error.log for the first "Bad header line": --- 8< ---------------------------------------------------- Sun Mar 20 15:48:27 2011|debug [13565]: Sending libcurl http://de.archive.ubuntu.com/ubuntu/dists/maverick/main/i18n/Translation-en.bz2 Sun Mar 20 15:48:27 2011|debug [13565]: Entering critical section : connect libcurl Sun Mar 20 15:48:27 2011|debug [13565]: Connection to running libcurl process found on /var/cache/apt-cacher/libcurl.socket Sun Mar 20 15:48:27 2011|debug [13565]: Exiting critical section Sun Mar 20 15:48:27 2011|debug [13566]: libcurl: connection from IO::Socket::UNIX=GLOB(0x97da768) Sun Mar 20 15:48:27 2011|debug [13566]: Libcurl: thawed request http://de.archive.ubuntu.com/ubuntu/dists/maverick/main/i18n/Translation-en.bz2, 1, Sun Mar 20 15:48:27 2011|debug [13566]: Init new libcurl object Sun Mar 20 15:48:27 2011|debug [13566]: Add curl handle #2: for http://de.archive.ubuntu.com/ubuntu/dists/maverick/main/i18n/Translation-en.bz2 Sun Mar 20 15:48:27 2011|debug [13566]: libcurl: setting up for HEAD request Sun Mar 20 15:48:27 2011|debug CURLINFO_TEXT [13566]: About to connect() to de.archive.ubuntu.com port 80 (#0) Sun Mar 20 15:48:27 2011|debug CURLINFO_TEXT [13566]: Trying 141.30.3.82...
