Running post - installation trigger cracklib-runtime 40%

[J]

I tried to install from the live session multiple times and it failed at the same point each time. "Running post - Installataion trigger cracklib - runtime 40%" is shown on the installer window. I have not tried any of the extra boot options like nomodeset.
