I tried upgrading again and that failed in the same way. Because I expected the possibility of this happening, I was able to collect useful debugging data about this bug. This appears to be the trouble:

Preparing to replace libssl0.9.8 0.9.8g-4ubuntu3.13 (using .../libssl0.9.8_0.9.8k-7ubuntu8.6_amd64.deb) ...

The upgrade continues for a while longer, ultimately completely failing because there's too many dependency problems.

It looks like my trouble is Bug #387112. I'll mark this report as a duplicate and upload new logs in case someone may find them useful.
