Yes, this is something that absolutely needs to be fixed. With the
multi-TB disks we have today, the installer should default to a
bigger /boot, when it creates it as a separate partition. I assume
there is still time to handle this before 15.10 goes into freeze, it
would be nice to have such a common problem fixed well before 16.04, as
that will be an LTS.

The OP wasn't clear on whether this is the problem, though, he just
said there was insufficient space for updates. It could be that the
root partition is full.

I expect that is the way it works. If so, he could manually remove the
older kernel before running the update.

That would indeed be helpful.

Couldn't have said it better myself :)

It *is* a problem that crops up way too often, though. And for new
users, it's confusing, and can be difficult to handle. Resizing
partitions is not something a new user should have to handle just to
get updates working.

I'm too lazy to check if there is a bug filed for this against ubiquity
- maybe later today.
