Since I rebuilt some Ubuntu packages such as pure-ftpd and ffmpeg, I think it would be better to keep the packages where I can get it back quickly whenever I need. I have a host for hosting my files. Anyway, the host is CentOS and it does not have any APT tools. In addtion, I don't know about Ubuntu or Debian repository. Fortunately, I found a good article and a good howto. The most important thing in Debian-based repository is its directory structure. What I have is as follow.

+-ubuntu/
  +-dists/
    |-breezy/
    | |-binary-i386/
    | | |-Release
    | | +-Package.gz
    | +-source/
    |   |-Release
    |   +-Source.gz
    +-dapper/
      |-binary-i386/
      | |-Release
      | +-Package.gz
      +-source/
        |-Release
        +-Source.gz

I moved all *_i386.deb files into binary-i386 and other files into source. Then, I need to generate index files for binary (Packages.gz) and source (Sources.gz) using dpkg tools.

$ dpkg-scanpackages binary-i386 /dev/null | gzip -9c > binary-i386/Packages.gz
$ dpkg-scansources source /dev/null | gzip -9c > source/Sources.gz

Next step is to create Release file to describe the origin, architecture and other meaningful information for each binary and source directory.

Archive: dapper
Component: contrib
Origin: ThaiGrid
Label: ThaiGrid Ubuntu repository
Architecture: i386

Now it should work by just adding below lines in /etc/apt/sources.list.

deb http://download.thaigrid.or.th/pub/ubuntu breezy contrib
deb-src http://download.thaigrid.or.th/pub/ubuntu breezy contrib

For more information, I recommend you to see live directory strucure at my repository.
