[buildd-tools-devel] Bug#824165: $apt_allow_unauthenticated = 1 in .sbuildrc breaks the chroot

[Raphaël Hertzog]

Package: sbuild
Version: 0.69.0-2
Severity: important

$ sbuild-update --update source:jessie-amd64-sbuild
source:jessie-amd64-sbuild: Performing update.
E: Syntax error /var/lib/sbuild/apt.conf:3: Malformed tag
Exiting from update with status 100.

And the broken /var/lib/sbuild/apt.conf looks like this:
$ cat /var/lib/sbuild/apt.conf 
APT::Get::AllowUnauthenticated "true";
"APT::Install-Recommends "false";
APT::AutoRemove::SuggestsImportant "false";
APT::AutoRemove::RecommendsImportant "false";
Acquire::Languages "none";

This seems to be related to my .sbuildrc which contains "$apt_allow_unauthenticated = 1;".

And this is confirmed by the code:

    if ($self->get_conf('APT_ALLOW_UNAUTHENTICATED')) {
        print $F qq(APT::Get::AllowUnauthenticated "true";\n");
    }

Notice the final quote while it's the parenthesis that ends the string...
