Ever since a few weeks ago, every time I try to add a source in Cydia, it goes to the black screen that says updating sources like always, but while its dowloading packages etc, errors from previous sources that hadnt worked pop up and it becomes stuck there and I have to force quit Cydia to make it go away. I have already tried going into cydia.list and deleting bad sources multiple times but it doesnt work. Anyone know whats up?
