Here are the additional steps if the above fail to fix crashing Cydia:
Downloaded and unzipped file (the above download link).
Connected iPhone to computer and backedup with iTunes.
Closed iTunes.
Ran .exe and clicked button.
When the program was finished, I disconnected the iPhone from the computer.A confirmation screen will appear shortly when it has finished.
or
Find the folder /var/lib/apt/lists (may have to backtrack to the var folder default log-in isnt always the root folder where var is)
I opted to back up all of the files I was deleting simply by dragging them to a folder on the desktop you dont have to, but having a way to undo stuff is usually a good option to have.
Delete all of the files except for the partial folder
Disconnect the SSH connection in your program
Restart cydia, done.
