After spending most of the afternoon stracing and perl-tracing this
sucker, I think I've traced the root cause of this issue to lines 45/46 in
dpkg-preconfigure:
open (STDIN, "/dev/tty") ||
(print STDERR sprintf("dpkg-preconfigure: ".gettext("unable to re-open stdin: %s"), $!)."\n", exit 0);
This is just after that command has read the packages to be preconfigured
from STDIN.
strace shows:
09:13:46 read(0, "/var/cache/apt/archives/popularity-contest_1.39_all.deb\n", 4096) = 56
09:13:46 read(0, "", 4096) = 0
09:13:46 open("/dev/tty", O_RDONLY|O_LARGEFILE) = -1 ENXIO (No such device or address)
And a trace of perl execution shows:
in $=Locale::gettext::gettext('unable to re-open stdin: %s') from /usr/sbin/dpkg-preconfigure:45
out $=Locale::gettext::gettext('unable to re-open stdin: %s') from /usr/sbin/dpkg-preconfigure:45
After removing the error check, the task installation runs normally with
templates getting extracted and packages preconfigured.
Note that for some reason that error message never makes it to the syslog!
This is one of the reasons that tracing this issue has taken so long.
