package roundcube-core 0.3.1-3 [modified: usr/share/roundcube/program/include/iniset.php] failed to install/upgrade: la subprocezo instalis skripton pre-removal liveris eraran elir-staton 1

Binary package hint: roundcube

I was uninstalling roundcube, I deleted the config files and the database, I inserted the password and debconf asked me what I wanted to do (Undo, retry). I selected retry and compared again debconf asking me if I wanted to install again roundcube. I said no and compared again the menu with retry or undo. I selected undo and the uninstallation goes on but the software crashed.
I hope you could underdstand

EDIT: Maybe it is because I inserted a wrong password: now I completely deleted RC by inserting another password.
