Pro Tip: If a tweak you loved from Cydia doesn’t appear in Sileo’s search after adding BigBoss, check the package’s compatibility. Tweaks from iOS 9 era will not work on iOS 14/15 without updates.

Cause: The repo is dead or the URL changed. Fix: Remove the repo immediately. Do not try to fix it.

The main repo (cydia.saurik.com) is not a standard package repository. It’s the front page of the old Cydia store. Adding it to Sileo will cause HTTP/1.1 404 or GPG errors because Sileo is looking for Packages files that don’t exist there.

Fix: Remove it immediately.

Enter Sileo—the modern, faster, and more user-friendly alternative.

If you have searched for the phrase "Cydia installer repo Sileo," you are likely in the middle of a transition. Perhaps you have a new jailbreak that uses Sileo (like Chimera, Odyssey, or Taurine) but you miss your old Cydia tweaks. Or maybe you prefer Cydia’s legacy but want to add Sileo’s repos.

This article will explain everything: How to install Sileo using Cydia, how to add Cydia’s default repositories to Sileo, and how to manage both package managers side-by-side.
