apt mirror chooses wrong architecture

I tried to do a repository mirror using apt-mirror and it inexplicably choose the wrong architecture. This is the architecture of the mirroring machine: uname -a Linux MyWorkStation 3.2.0-76-generic #111-Ubuntu SMP Tue Jan 13 22:16:09 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux head /proc/cpuinfo processor : 0 vendor_id : GenuineIntel cpu family : 6 model : 44 model name : Intel(R) Xeon(R) CPU X5690 @ 3.47GHz stepping : 2 microcode : 0x10 cpu MHz : 3458.056 cache size : 12288 KB physical id : 0 This is what my /etc/apt/mirror.list looks like: ############# config ################## # # set base_path /var/spool/apt-mirror # # set mirror_path $base_path/mirror # set skel_path $base_path/skel # set var_path $base_path/var # set cleanscript $var_path/clean.sh # set defaultarch # set postmirror_script $var_path/postmirror.sh # set run_postmirror 0 set nthreads 20 set _tilde 0 # ############# end config ############## deb http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu precise-security main restricted universe multiverse deb http://archive.ubuntu.com/ubuntu precise-updates main restricted universe multiverse #deb http://archive.ubuntu.com/ubuntu precise-proposed main restricted universe multiverse #deb http://archive.ubuntu.com/ubuntu precise-backports main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu precise main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu precise-security main restricted universe multiverse deb-src http://archive.ubuntu.com/ubuntu precise-updates main restricted universe multiverse #deb-src http://archive.ubuntu.com/ubuntu precise-proposed main restricted universe multiverse #deb-src http://archive.ubuntu.com/ubuntu precise-backports main restricted universe multiverse clean http://archive.ubuntu.com/ubuntu The mirror that was created was only amd64 binaries, no i386. Where is it going wrong?
