apt could not exec dpkg

["Hongzheng Wang" <wanghz@gmail.com>]

Hi all,

I'm new to this mailing list.  I upgraded a Debian Hurd system
recently and encountered some problems with apt and dpkg.  Each time
when I use apt to install/upgrade packages, it always fails after
downloading packages and beginning to call dpkg to handle them:

Preconfiguring packages ...
Could not exec dpkg!
E: Sub-process /usr/bin/dpkg returned an error code (100)

But if I mannually execute dpkg to handle the cached packages under
/var/cache/apt/archives/, dpkg works properly.  And this problem does
not exist several weeks before.  Related system and packages
information follows:

GNU hurd 0.3 GNU-Mach 1.3.99/Hurd-0.3 i686-AT386 GNU

ii  hurd        20071119-1
ii  gnumach     2:1.3.99.dfsg.cvs20070809-1
ii  dpkg        1.14.16.6
ii  dpkg-dev    1.14.16.6
ii  apt          0.7.10
ii  apt-utils   0.7.10
ii  libc0.3     2.7-7


By the way, I have also report it as a bug #466268, but I think it
might be better to post it on mailing list.  So this post appears.

Thanks.
