package cryptsetup 2:1.6.6-5ubuntu2 failed to install/upgrade: subprocess installed pre-removal script returned error exit status 1

Hello!
I did install gdm and get into trouble
I could not wait any more because A start job is running for Halt... bla-bla-bla... (20m1s no limit)
I runned
# apt-get remove plymouth
# apt-get remove lightdm
# reboot
# apt-get -f install
# apt-get install lightdm
I have choosen lightdm as default dm
# apt-get install ubuntu-desktop
# reboot
Now I have solved this problem and writing this text into firefox, but before firefox I had got a window where was "A system programm has done an error" or something like that and pressed "report" or something like that.
