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

[Benjamin Drung (bdrung)]

Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:

E: No boot partition found !

The df log does not show any mounted /boot partition. Can you check if you have a separate boot partition and mount that?
