Unable to properly install 2 packages

["J.F.Gratton" <grajea01@hotmail.com>]

Hi all,

I've never been good to fix packages that break down at install (I'm not
blaming maintainers for the packages, btw... I guess I'm responsible for
the mess here).

Here's what happened :

-----
helsinki:~# apt-get dist-upgrade
Reading Package Lists... Done
Building Dependency Tree... Done
Calculating Upgrade... Done
0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
2 not fully installed or removed.

Setting up guile-1.6 (1.6.7-1) ...
dpkg (subprocess): unable to execute post-installation script: Exec
format error
dpkg: error processing guile-1.6 (--configure):
 subprocess post-installation script returned error exit status 2
dpkg: dependency problems prevent configuration of libgwrapguile1:
 libgwrapguile1 depends on guile-1.6; however:
  Package guile-1.6 is not configured yet.

E: Sub-process /usr/bin/dpkg returned an error code (1)

How do I get out of the "Exec format error" ?

On a related topic : is there a way to make apt "forget" a package,
and/or completely purge it from the disk, its installed packages list,
etc ? Just so I'd be able to reinstall it or a newer version sometime
later ?


Thanks,

Jeff
