Ubiquity - apt configuration problem

[vmc]

Binary package hint: ubiquity

I used "Startup Disk Creator" to create a USB flash installer.
Ubiquity t installer at around 79%, "Configuring apt" I run across "apt configuration problem".
 Ubiquity waits until I push ok before it continues.

See attachment for screenshot. Also attached is installer debug from /var/log/installer.

The ERROR occurs around this time. I provided a snapshot of the time window, below from "debug" file:

Can you please attach /var/log/installer/syslog from the installed machine (or /var/log/syslog from the live environment after the error, if you're installing again)? I suspect this is a duplicate of bug 534473, but wont know for sure until I see the syslog.

Yes, I just re-installed and have "/var/log/syslog" from live environment. Also its /var/installer/debug as well.

====================================
Right at the point of failure I captured "debug" messages:

The complete files from the live install, for "syslog" and "debug" are attached.

This has been fixed with using todays live-daily MAR18th.

No "apt configuration problem" dialog.
