Howto create your own Ubuntu repository

Linux | Debian

Ubuntu and Debian packages are all bundled in something what is called a repository. Some people, like me, create their own:

Note:

My repository links with the Jaunty distribution (that is Ubuntu 9.04). Your can connect yours to any other, like Debians experimental repository.

First create your own repository.

My repository is accessible over the web, so I installed it on my web server:

user@box:~$ cd /var/www/
user@box:/var/www$ sudo mkdir packages
user@box:/var/www$ cd packages/

In this /var/www/packages we will create a pool, the 'jaunty' distribution and the cache directories:

user@box:/var/www/packages$ sudo mkdir -p pool/main
user@box:/var/www/packages$ sudo mkdir -p dists/jaunty/main/binary-i386
user@box:/var/www/packages$ sudo mkdir .cache

Now two files need to be created. The first one is the apt-release.conf. Make sure that it looks like:

APT::FTPArchive::Release::Codename "jaunty";
APT::FTPArchive::Release::Origin "elevenbits.com";
APT::FTPArchive::Release::Components "main";
APT::FTPArchive::Release::Label "ElevenBits Ubuntu Repository";
APT::FTPArchive::Release::Architectures "i386";
APT::FTPArchive::Release::Suite "jaunty;

The second file is called apt-ftparchive.conf. This one should look like:

Dir {
     ArchiveDir ".";
     CacheDir "./.cache";
};

Default {
     Packages::Compress ". gzip bzip2";
     Contents::Compress ". gzip bzip2";
};

TreeDefault {
     BinCacheDB "packages-$(SECTION)-$(ARCH).db";
     Directory "pool/$(SECTION)";
     Packages "$(DIST)/$(SECTION)/binary-$(ARCH)/Packages";
     Contents "$(DIST)/Contents-$(ARCH)";
};

Tree "dists/jaunty" {
     Sections "main";
     Architectures "i386";
}

After you'd created these file your system should look like this:

user@box:/var/www/packages$ ls -al
total 28
drwxr-xr-x 5 root root 4096 Aug 14 13:32 .
drwxr-xr-x 3 root root 4096 Aug 14 13:22 ..
drwxr-xr-x 2 root root 4096 Aug 14 13:26 .cache
-rw-r--r-- 1 root root  427 Aug 14 13:32 apt-ftparchive.conf
-rw-r--r-- 1 root root  282 Aug 14 13:30 apt-release.conf
drwxr-xr-x 3 root root 4096 Aug 14 13:26 dists
drwxr-xr-x 3 root root 4096 Aug 14 13:26 pool

Add your own packages and update the repository.

Here the yourpackage package version 1.0 is copied into the new (empty) repository:

user@box:~$ cd /var/www/packages/pool/main
user@box:/var/www/packages/pool/main$ sudo cp ~/yourpackage_1.0_all.deb .

Now the repo needs to be initialized. This you can do using these commands:

user@box:~$ cd /var/www/packages
user@box:/var/www/packages$ sudo apt-ftparchive generate apt-ftparchive.conf
 pool/main: 1 files 9900B 0s
Done Packages, Starting contents.
 dists/jaunty/Contents-i386: 1 files 9900B 0s
Done. 9900B in 1 archives. Took 0s
user@box:/var/www/packages$ apt-ftparchive -c apt-release.conf release dists/jaunty | sudo tee dists/jaunty/Release

After this, the repository is ready to be used. See http://localhost/packages to make sure.

Note:

Remember to re-initialize the repo each time the /var/www/packages is altered.

Enable the repository on your client machines.

On the Ubuntu machines that need access to your repository, use

sudo vim /etc/apt/sources.list

to add in the repository address:

deb http://ww.xx.yy.zz/packages jaunty main

where ww.xx.yy.zz is the address where your server lives.

From now on the system has access to our own private repository. Cool, no?
