[Bug 1357093] Re: Kernels not autoremoving, causing out of space error on LVM or Encrypted installation or on any installation, when /boot partition gets full

[Jarno Suni]

stub,

I suppose the upgrading process did not change the settings concerning
unattended-upgrade. You should do that manually after upgrading from
14.04 and initially remove extra kernels manually before upgrading.


de0u,

I tell about the restrictions concerning 'apt-get autoremove' in the wiki page. Likewise I tell about some alternatives not limited to 'purge-old-kernels'. I think it is harsh to say most things do not work, if you do not specify.
You could run Unattended-upgrade from command line to install new kernel updates when you want:

sudo apt-get update && sudo unattended-upgrade

As for un-clogging, did you read the 'Safely Removing Old Kernels'
chapter? I see many people take time to complain, but I see none who is
willing to spend even 1$ to get an easier solution for poor Ubuntu
users.

Title:
  Kernels not autoremoving, causing out of space error on LVM or
  Encrypted installation or on any installation, when /boot partition
  gets full

Status in unattended-upgrades:
  New
Status in unattended-upgrades package in Ubuntu:
  Fix Released

Bug description:
  Currently if one chooses to use LVM or encrypted install, a /boot
  partition is created of 236Mb

  Once kernel updates start being released this partition soon fills
  until people are left unable to upgrade.

  While you and I might know that we need to watch partition space, many
  of the people we have installing think that a windows disk is a disk
  and not a partition, education is probably the key - but in the
  meantime support venues keep needing to deal with the fact the
  partition is too small and/or old kernels are not purged as new ones
  install.
