This page contains instructions for getting a personal repository set up, and general tips and tricks.

Setup

Novice

If you have no interest in setting up your own server, you can always use MyRepoSpace. It can be a little slow though.

Advanced

Cydia uses a Debian APT-like implementation to manage packages.

saurik's explanation

If you have no experience with Debian APT, you can read saurik's excellent writeup on the subject, which is pretty comprehensive.

Quick and dirty summary

First thing is, you'll need a web host. It could be anything, like Neocities or GitHub pages.

Repository structure

The basic idea is that you have two files in your server, Packages and Release. Packages must be bzipped and named Packages.bz2, and optionally Release may be also. Packages contains all of the information related to the different packages on your server (and where to download them, more on that later) and Release contains all of the information related to your server (like the name, description, etc).

If you want to see examples of Packages and Release files, you can see the cached files from your installed repos at /var/lib/apt/lists (note they can be quite large).

.deb files

The Packages file mentioned earlier points to .deb files in your server that you can download. These are made with dpkg-deb. Manpage here. The idea is that you set up a folder in the way you'd want the files to appear in your filesystem (and the DEBIAN folder, which would contain your control file, and optional preinst and postinst scripts) when it installs in Cydia, and then you'd use dpkg-deb -b folder_name to make the package (which will be named folder_name.deb).

Custom icon

Put the file CydiaIcon.png at the root of your repository.

Private repos

The easiest way to make your repository "private" is to restrict access based on UDID. Cydia sends the user's UDID via the X-Unique-ID HTTP header, so your server could check that against a database in order to ensure that the user has rightful access.

NOTE: Static webhosts like Neocities won't work for private repos. You'll need a server that has some way to let you process requests server-side, e.g. PHP, node.js, or Flask.
