I have a problem like this. This started to happen after I tryed to add a repo to Cydia. The repo was cydia.bananas.com. Because of this problem I can't view my sources or packages that I downloaded from Cydia in Cydia. I tried to delete the source/package from iFile in the folder /var/lib/apt/lists and then when I went to Cydia and when it loaded everything worked. But after I got out of Cydia and went back on it started to load the Data and then it just recreated the source cydia.bananas.com in my /var/lib/apt/lists folder and it then says again in Cydia Encountered a section with no Package: header. How can I fix this. How can I delete cydia.bananas.com source completly without Cydia recreating it the next time I boot it up.
