The file /lib/modules/2.6.22-15-generic/modules.dep mysteriously went
missing from my machine. Either it never got installed or it somehow
got deleted. The way I discovered this is that running:
(actually in a script, but I tested afterwards again just this line)
failed for the first time with a new error:
Failed to setup dm-crypt key mapping
similar to the one described at
(though I think the cause is unrelated).
Needless to say, losing the encrypted data would not be a fun time.
Anyway, I ran:
modprobe -l *cryptsetup*
and got an error that /lib/modules/2.6.22-15-generic/modules.dep was not
linux-image-2.6.22-15-generic fixed the original problem and the error
with modprobe (note as I discovered the actual module is dm-crypt, but
modprobe -l should never give an error for a bad module; it just doesn't
So my question is, what could have caused this file to go missing, and
should I be concerned?
