Comment 4 for bug 44796

I had the same problem upgrading from Breezy to Dapper. My system seemed fine on reboot (except that I will need to recompile the driver for my graphics card against the new kernel, so I'm down from two monitors to one at the moment).

The error was as follows (I'll attach the logs separately):

A fatal error occured

Please report this as a bug and include the files /var/log/dist-upgrade.log and /var/log/dist-upgrade-apt.log in your report. The upgrade aborts now.
Your original sources.list was saved in /etc/apt/sources.list.distUpgrade.
