Package: linux-image-2.6.21-1-686
Version: 2.6.21-4
Severity: important


I'm using debian unstable. Since some time ago, when I try to upgrade my kernel (like: aptitude install 
linux-image-2.6.21) i get the message:

Could not find postinst hook script [usr/sbin/update-grub].
Looked in: '/bin', '/sbin', '/usr/bin', '/usr/sbin'
dpkg: error processing linux-image-2.6.21-1-686 (--configure):
 subprocess post-installation script returned error exit status 2
Errors were encountered while processing:
 linux-image-2.6.21-1-686


The problem lies on the sub run_hook on the postinstall script.

The trouble part is that:

    # Look for it in a safe path
    for my $path ('/bin', '/sbin', '/usr/bin', '/usr/sbin') {
      if (-x "$path/$script") {
        &exec_script($type, "$path/$script");
        return 0;
      }
    }

If I strip the path thing from the script like that:

        &exec_script($type, "$script");

it works ok.

as expected passing faulty values here.
aboves is not a correct path, you'd need to have on both lines
/usr/sbin/update-grub
