Public bug reported:
running "apt-get dist-upgrade" to upgrade from hardy to integrity,
debconf.prerm script failed. I added "-x" to the debconf.prerm script
and re-ran the dpkg command and it failed again the same way:
[EMAIL PROTECTED]:/var/cache/apt/archives # dpkg -i debconf_1.5.21_all.deb
(Reading database ... 135672 files and directories currently installed.)
Preparing to replace debconf 1.5.20 (using debconf_1.5.21_all.deb) ...

+ awk $0~/\.py$/ {print $0"c\n" $0"o"}
+ tee /dev/tty
+ xargs rm -f

dpkg: error processing debconf_1.5.21_all.deb (--install):
subprocess new pre-removal script returned error exit status 134
Errors were encountered while processing:
debconf_1.5.21_all.deb
So xargs was hosed by something in the upgrade. NFC. I then replaced the use of
xargs since it was only a few files that were to be removed:
while read x
do
rm -f $x
done
I have NFC why xargs failed and honestly don't care. debconf failing
during a dist-upgrade just shouldn't be possible and not using xargs
reduces the odds of that by a bit. awk b0rkage is still a bigger risk
(more code than xargs I expect).
