I also get the "command failed" message when update-initramfs is run,
this is occuring in the cryptroot hook script (/usr/share/initramfs-
tools/hooks) when it tries to get info about the dependent devices.
The system does not have an encrypted root partition, but does use LVM
and this is possibly causing the issue.
Another possible bug in the cryptroot script is the regex for
determining major minor, this is only pulling out a single digit for the
minor (my system has a double digit minor) so the sed line should be as
follows (unless there is some reason to only want the first digit of the
minor)
majorminor=$( dmsetup deps $node | \
sed 's/[^:]*: *(\([0-9]*\), *\([0-9]*\).*/\1 \2/') ||
return
After altering this, it still fails to find the dependancy node
depnode=$( dmsetup info -c --noheadings -j $major -m $minor | cut -d ":"
-f 1 )
the major/minor is 8, 17 which is correctly determined, but this does not match
any devices
dmsetup deps Ubuntu-root
2 dependencies : (8, 17) (8, 5)
here is the full info list

This shouldnt be a fatel issue (particularly since I dont have a cryptroot, but
I did have one of the installed kernels hang after initramfs had that error,
not sure if its related but I have some work to get done before I reboot and
see if my working kernel has died now :)
