Setting -x did not produce any useful result; stdout shows the usual:

I: Unpacking debconf...
I: Unpacking debianutils...
I: Unpacking libdevmapper1.02.1...
I: Unpacking diff...
W: Failure while unpacking required packages.  This will be attempted
up to five times.

...meanwhile, tailing the log shows a neverending series of these:

+ echo ''
+ :
+ echo ''
+ :
+ echo ''
+ :
+ echo ''
+ :
+ echo ''
+ :
+ echo ''

...which I presume to be debconf's way of "pressing Enter" into dpkg?
Not very useful tracing info, anyhow.

I suppose this leaves tracking this with strace as a last resort.
However, I cannot remember if strace is actually capable of tracking
shell scripts?
