Public bug reported:

I haven't installed anything special in terms of kernel modules or
anything so the default configuration the installer left me with should
have been fine. However it was not, today I encountered a problem when
running "sudo apt-get dist-upgrade":


After some investigating I found that it was caused by the fact that the
"/boot" directory size is capped on its partition at too small a size.

This was the output from "df -h":

Filesystem                          Size  Used Avail Use% Mounted on
udev                                1.9G     0  1.9G   0% /dev

tmpfs                               381M   20K  381M   1% /run/user/120
tmpfs                               381M   56K  381M   1% /run/user/1000

But "ls /boot" revealed nothing unusual in there:

abi-4.4.0-34-generic                  lost+found
abi-4.4.0-36-generic                  memtest86+.bin
abi-4.4.0-38-generic                  memtest86+.elf

grub                                  vmlinuz-4.4.0-34-generic

initrd.img-4.4.0-36-generic.old-dkms  vmlinuz-4.4.0-38-generic

So to prevent myself and other users installing with the default UEFI
mode from needing to do manual partitioning or kernel module removal
when doing this kernel upgrade or one in the future, the default size
for "/boot" should be larger.

I am running Ubuntu GNOME 16.04.1 with GNOME 3.20.

  Default size for "/boot" with UEFI mode too small and causes problems
