This might be aggravated by this DKMS bug which was found in v2.2.0.3, which incidentally is used in Ubuntu 16.04 LTS, and maybe other versions. It doesn't remove old initrd files in /boot *which lead to full /boot issues and subsequent update problems*
I manually removed a bunch of old initrd images the other day. http://askubuntu.com/questions/616512/purging-old-kernels-fails-to- remove-old-initrd-files https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717584 ** Bug watch added: Debian Bug tracker #717584 http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=717584 -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to unattended-upgrades in Ubuntu. https://bugs.launchpad.net/bugs/1357093 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.
