Same for me with Ubuntu MATE 17.04 → 17.10 (final, not beta). The dialog appeared multiple times and at the end of the process I got a message saying that the upgrade failed. I tried to finalize it with sudo dpkg --configure -a and sudo apt-get install, tried to force a reinstall of this package (sudo apt-get install --reinstall cracklib-runtime) and it all went well after a reboot.
