[buildd-tools-devel] Bug#823993: sbuild: bad foreach when reading the list of foreign architectures

[Adam Borowski]

Package: sbuild
Version: 0.69.0-1
Severity: normal

When there's actually a foreign arch configured, I get:

[~]# sbuild-update -udcar unstable-arm64
Use of uninitialized value $_ in scalar chomp at /usr/share/perl5/Sbuild/ResolverBase.pm line 192.
unstable-arm64: Performing update.
(..., all ok, exit status 0)
[~]# chroot /srv/sbuild/unstable-arm64/
(unstable-arm64-sbuild)root at umbar:/# dpkg --print-foreign-architectures
amd64
(unstable-arm64-sbuild)root at umbar:/#

And the code in question is:
    foreach my $arch (split /\s+/, $foreignarchs) {
        chomp;
        next unless $_;
        $set{$_} = 1;
    }

Note "my $arch" vs "$_".
