I have been hosting my app on a cydia repository for quite some time, and haven't had any problems hosting the app for iOS 5 or iOS 6. However, when I upgraded one of my devices to iOS 7, and tried to install the app it gave me some errors during the installation.
The erros I am getting are,
subprocess dpkg-deb --fsys-tarfile returned error exit status 2
Sub-process /usr/bin/dpkg returned an error code (1)
Apparently there's some compatibility issues with
Cydia, and the homebrew release of
dpkg. I ended up finding this, which solved the install problem. :)
