Hi,
I don't know if this is the right sub-forum as I'm new here, but I hope it is.
Few days ago I realized that one of my tweaks said that the license was missing, so I opened Cydia to reinstall it.
However, I got an error in the process of installment.
Code:
subprocess pre-installation script returned error code exit status 1
Sub-process /usr/bin/dpkg returned an error code (1)
Didn't know what this was about, I tried rebooting, respringing, using the tweak iCleaner despite knowing it wouldn't solve it, and searched some ways to solve the problem on the Internet.

I ended up deleting few files through iFile. Although the error doesn't appear anymore, I got another one.
Code:
Couldn't configure pre-depend dpkg for ncurses, probably a dependancy cyle.
I absolutely have no clue about this error.
Any sugguestions apart doing again the Jailbreak would be greatly apreciated. Thanks.
And also, I would like what causes both of the errors and how to solve the in case of a future need or for other members in the forum.
