Binary package hint: ubiquity

ausu P7P55D motherboard , i5-750cpu
did not format partition, let it delete a Slackware OS
it wiped it and installed Mint 8 32bit , 1.7g of stuff before it spat
It completed approx 85% of install and came up with the error popup, below.
Apology, could not read your guidlines as I was not on the net, had to reboot back to Mint 7 to do this.

We're sorry; the installer crashed.
