Ever since the evasi0n jailbreak came out, we’ve been inundated with the same support request about a Cydia error that displays the following message: wow, you exceeded the number of package names this APT is capable of. The message also shows a couple more lines of errors but the first one really is the source of the problem. In this post, we’ll explain what “the number of package names this APT is capable of” means, and most importantly, we’ll provide you with a quick and simple fix for it…
You may, or may not have known this, but there’s a glitch in iOS 6.1.x that can cause your Contacts application to crash unexpectedly. A new free jailbreak tweak called Contact Fix for 6.1.x by iOS developer yeahwangy is available in Cydia as of Wednesday afternoon that fixes the problem and keeps the Contacts application from crashing when you change a contact’s picture in the way explained above.
You may proceeded successfully and smoothly when jailbreak, installing tweaks is also a risk. If you happened to touched a tweak that is not yet compatible with iOS 6, it would make your device go into a endless boot loop. In this case restoring is not the only solution. MobileSubstrate features a failsafe to correct the situation. Take a look saving solusions from folks over iJailbreak.
If you are still getting errors in Cydia, you can try installing .deb packages manually through Cydia’s AutoInstall folder. The problem is finding the tweaks and packages when the repos can’t be reliably accessed through the Cydia app. One workaround I’ve found effective is to search for the direct links for packages through an indexing site, like CydiaUpdates.net.
