Package: apt-cacher-ng Version: 0.5.1-3 Severity: normal Tags: upstream I'm using apt-cacher-ng behind a corporate proxy. When I run apt-get update on a client machine I get random errors like the following:
W: Failed to fetch http://apt-cacher-ng-host:3142/debian/dists/testing/main/binary-amd64/Packages.bz2 Hash Sum mismatch W: Failed to fetch http://apt-cacher-ng-host:3142/debian/dists/unstable/main/source/Sources.bz2 Hash Sum mismatch W: Failed to fetch http://apt-cacher-ng-host:3142/debian/dists/unstable/non-free/binary-amd64/Packages.bz2 Hash Sum mismatch This is because the apt-cacher-ng cache contains incoherent files. For example a Release file of the day and a Release.gpg file of the day before. If I use apt-get through my corporate proxy, without apt-cacher-ng everything is ok. I compared apt-cacher-ng and direct apt-get HTTP traffic and found that apt-cacher-ng miss a Cache-Control field in each HTTP headers. I made the following changes in the source: --- a/source/dljob.cc +++ b/source/dljob.cc @@ -125,7 +125,8 @@ bool tDlJob::AppendRequest(string sForThisHostOnly, tSS &head) head << (m_pStorage->m_bHeadOnly ?

It would be nice to allow to configure the content of the Cache-Control field in the acng.conf file (apt.conf have it). -- System Information: Debian Release: wheezy/sid APT prefers testing APT policy: (900, 'testing'), (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/8 CPU cores) Locale: LANG=C, LC_CTYPE=C (charmap=ANSI_X3.4-1968) Shell: /bin/sh linked to /bin/dash Versions of packages apt-cacher-ng depends on: ii adduser 3.112+nmu2 add and remove users and groups ii debconf [debconf-2.0] 1.5.38 Debian configuration management sy ii libbz2-1.0 1.0.5-6 high-quality block-sorting file co ii libc6 2.11.2-11 Embedded GNU C Library: Shared lib ii libfuse2 2.8.4-1.1 Filesystem in USErspace library ii libgcc1 1:4.4.5-10 GCC support library ii libstdc++6 4.4.5-10 The GNU Standard C++ Library v3 ii zlib1g 1:1.2.3.4.dfsg-3 compression library - runtime Versions of packages apt-cacher-ng recommends: ii ed 1.4-3 The classic UNIX line editor ii perl 5.10.1-17 Larry Wall's Practical Extraction apt-cacher-ng suggests no packages. -- Configuration Files: /etc/apt-cacher-ng/security.conf [Errno 13] Permission denied: u'/etc/apt-cacher-ng/security.conf' -- debconf information excluded -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
