[Bug 220094] Re: initramfs-tools trigger fails if modules aren't installed

[Tristan Schmelcher]

I also experienced this issue (in Lucid) with a kernel whose package had
since been removed. I found by strace'ing update-initramfs that it gets
the kernel list from the contents of /var/lib/initramfs-tools/. There's
one entry there per kernel. Deleting the one for my removed kernel fixed
the problem.

Title:
  initramfs-tools trigger fails if modules aren't installed

Status in tools for generating an initramfs:
  New
Status in “initramfs-tools” package in Ubuntu:
  Confirmed

Bug description:
  I upgraded a system from gutsy to hardy. Before starting the do-
  release-upgrade -d, I removed all the kernel and modules packages that
  were installed under gutsy (I use my own kernel, because 2.6.24 has
  kernel bug 10118, and I was running out of disk space on /boot).

  During the "setting up" stage, I hit problems: apt refused to do
  anything further and told me to run dpkg --configure -a. but dpkg
  --configure -a failed because the initramfs-tools trigger couldn't
  find the appropriate /lib/modules directory.

  I eventually found a workaround: 
  rm /var/lib/dpkg/triggers/initramfs-tools

  If initramfs-tools can't install without kernel modules installed,
  shouldn't it have a dependency on some modules package? Or, better
  still, maybe have the initramfs-tools trigger exit gracefully if it
  doesn't see any modules.
