I had tried looking for the source but it's not in the source menu. Is there any way to resolve the problem?Go into Cydia and go to Manage > Sources and delete the source from there.
I was finally able to see things in iFile in /var/lib/apt/lists to delete everything but the partial folder, but I still have been getting the 'Encountered a section with no Package: header. Any suggestions? If you want me to start a new thread, I will. @Europa @Napoleon PhoneApartYou can manually navigate to /etc/apt/sources.list.d/ and edit out the sources in cydia.list, or delete the appropriate .list file.
Then go to /var/lib/apt/lists/ and delete everything but the partial folder, and the lock file.
