Comment 5 for bug 1506364

Stumbled over the same issue.

It failed with 128MB site for /boot but worked with 150MB size.

What is this package unpacking that 128MB is not enough?! I also noticed that after the initial error messagesbox that tells you about initramfs-tools, there is another one (maybe from the finished installation in the background?) that shows that dpkg faild with exitcode (1) due to the following packages: -> and then no package is listed.

Seems like this error-reporting also did not work.
