Status changed to 'Confirmed' because the bug affects multiple users.

Installation continued after error was thrown. Appeared to complete, except that it exited with a generalized error message that some programs could not be installed. Moreover, instead of saying it could not write to the error log as it usually does, this time it said that no error log was found.

Not, apparently a killer.

I preceded this update with:
bill@bill-110-210:~$ sudo rm /boot/*[33,41]-generic (always trying to maintain 2 known-good installs prior to upgrading.

ls /boot appears to show a completed install.

Um ... it happened again.

Since so few others have reported this issue, I'm guessing that I must be doing something wrong. Would anyone care to volunteer a guess as to what that might be? I'm not afraid of the CLI but my Linux Guru cap got lost at the dry cleaners.
