I can confirm this error, and have identified the cause: there is a typo in the preinst script of this new package.
On my (English, 64-bit) system, I see: Preparing to replace alsa-base 1.0.19.dfsg-3ubuntu1 (using .../alsa-base_1.0.20+dfsg-1ubuntu1_all.deb) ... dpkg (subprocess): unable to execute new pre-installation script: Exec format error dpkg: error processing /var/cache/apt/archives/alsa-base_1.0.20+dfsg-1ubuntu1_all.deb (--unpack): subprocess pre-installation script returned error exit status 2 Errors were encountered while processing: /var/cache/apt/archives/alsa-base_1.0.20+dfsg-1ubuntu1_all.deb E: Sub-process /usr/bin/dpkg returned an error code (1) Manually unpacking the deb file with `ar`, and untarring the resulting control.tar.gz, I find that the pre-inst script inside the package begins: \#!/bin/sh Which is clearly wrong.
