[Bug 798414] Re: update-initramfs should produce a more helpful error when there isn't enough free space

[Gordon]

I'm still having this issue on Ubuntu Studio lowlatency kernel updates
using the following cmds:

sudo apt-get update
sudo apt-get autoremove
sudo apt-get autoclean
sudo apt-get dist-upgrade

Then it fails, seems to recover, not entirely convinced :(

Is there a way to safely increase the boot partion ?

Using an SSD drive...

df -h

/dev/sda1                               236M  227M     0 100% /boot


Please help... this always occurs and has been for what seems months.

Thanks

Title:
  update-initramfs should produce a more helpful error when there isn't
  enough  free space

Status in initramfs-tools:
  Confirmed
Status in initramfs-tools package in Ubuntu:
  In Progress

Bug description:
  Binary package hint: initramfs-tools

  When generating a new initramfs there is no check for available free
  space, subsequently its possible for update-initramfs to fail due to a
  lack of free space.  This is resulting in package installation
  failures for initramfs-tools.  For example:

  Setting up initramfs-tools (0.98.8ubuntu3) ...
  update-initramfs: deferring update (trigger activated)
  Processing triggers for initramfs-tools ...
  update-initramfs: Generating /boot/initrd.img-2.6.38-8-generic

  gzip: stdout: No space left on device
  E: mkinitramfs failure cpio 141 gzip 1
  update-initramfs: failed for /boot/initrd.img-2.6.38-8-generic
  dpkg: error processing initramfs-tools (--configure):
   subprocess installed post-installation script returned error exit status 1

  WORKAROUND:

  Remove unused kernels using computer janitor (not in repositories for
  14.04 or later) or manually free space on your partition containing
  the /boot file system.
