Hello, I believe this bug is fixed.
/usr/share/perl5/Sbuild/ChrootSetup.pm shipped with libsbuild-perl
0.65.0-1 has:
# Secret keyring needs to be readable by 'sbuild' group.
@command = ('chmod', '640',
$conf->get('SBUILD_BUILD_DEPENDS_SECRET_KEY'));
$host->run_command(
{ COMMAND => \@command,
USER => $conf->get('BUILD_USER'),
PRIORITY => 0,
DIR => '/'});
return $?;
