emdebian-tools.postinst

I tried several ways to identify the problem, but my knowledge is more psychology than programming.

However, the system is making the updates and gradually is upgrading.
Some programs doesn't work yet, but I think that in next month The Gutsy is here.

The last update:
A instalar emdebian-tools (0.2.0) ...

Unable to determine apt-cache policy for Debian main! at /var/lib/dpkg/info/emdebian-tools.postinst line 132.
dpkg: erro processando emdebian-tools (--configure):

This is a bug in emdebian-tools' postinst script. It is not security related at all, it just means that the package is not installable.

I solved the problem adding a debian repository to my sources.list, although maybe you don't want to do that.

I can confirm this one on Gutsy Gibbon.

Setting up emdebian-tools (0.2.0) ...
Unable to determine apt-cache policy for Debian main! at /var/lib/dpkg/info/emdebian-tools.postinst line 132.
dpkg: error processing emdebian-tools (--configure):

I've slove the probleme by hacking scriptt in an ugly way.
----------
for /var/lib/dpkg/info/emdebian-tools.postinst
change line 123 like this
  && /^\s+release v=7.10,o=Ubuntu,a=(\w+),l=Ubuntu,c=main\s*$/) {
and line 134 add
$suite = "unstable";

----------

and for /usr/share/perl5/Emdebian/Tools.pm
line 265
replace en get_suite like this :
sub get_suite()
{
        # list of suites supported by Emdebian toolchain repository.
        my @suites = qw/unstable testing stable sid etch/;
# hack for ubuntu user
# my $policy = `apt-cache policy 2>/dev/null | grep "l=Debian,c=main"`;
# croak ("Unable to determine apt-cache policy: $!") if (!$policy);
# $policy =~ /o=Debian,a=([a-z]*),l=Debian,c=main/;
# my $suite = $1;
        my $suite = "unstable";
        foreach my $s (@suites)
        {
                # check the matched value is sensible.
                return $s if ($suite eq $s);
        }
        $suite = &check_dist if ($suite eq "");
        return $suite;
}

I confirm this is a problem.

The hack given below seems to work ( at least post-install finishes correctly )

For me the importance of this bug is should be HIGH, since it breaks apt.

Please see.
