Package: apt-cacher
Version: 1.5.3
Severity: important
This single, flat cache directory causes problems if you
try to use apt-cacher for Ubuntu as well as Debian. For
example, both Debian Etch and Ubuntu Gutsy ship a package
called "xfonts-knickers". Both of them call the file
xfonts-knickers_0.0.1-3.1_all.deb, but the files are NOT
the same; etch's version is 9120 bytes and Ubuntu's is
9156 bytes. Downloading one distro's file overwrites the
others and causes problems.
Ideally, apt-cacher will use different subdirectories for
different releases. I realize this is tricky, if not impossible,
but it would be nice.

Thanks for this.
This is a duplicate of bugs #354925, #366624 and #415398. They are
closed as there is a suggested work around for this in README.Debian
since 1.5.5. The relevant extract reads:
MULTIPLE REPOSITORIES:
It has been requested that apt-cacher support being used on a network that hosts
both Debian and Ubuntu boxes. There are frequent namespace clashes between the 2
distributions which have files with identical names, but different
contents. This problem was not envisaged in the original design of apt-cacher
and is difficult to accommodate.
However, it is possible to workaround this by running a separate apt-cacher
daemon for each Distribution on a different port with its own cache
directory. The first daemon will run from /etc/init.d/apt-cacher as normal. For
the second daemon, run it from /etc/rc.local with command line options to
override the configuration file. Alternatively, run the daemons from
/etc/inetd.conf:
Example command-lines are:
apt-cacher daemon_port=3142 cache_dir=/var/cache/apt-cacher-debian
allowed_locations=ftp.debian.org/debian
and
apt-cacher daemon_port=3141 cache_dir=/var/cache/apt-cacher-ubuntu
allowed_locations=archive.ubuntu.com/ubuntu
It is important to set the allowed locations directive so that each daemon
only caches a particular distribution. This can be combined with the path_map
option:
path_map=debian ftp.debian.org/debian allowed_locations=debian
and
path_map=ubuntu archive.ubuntu.com/ubuntu allowed_locations=ubuntu
to provide a convenient interface for clients.
I hope this helps.
Mark
