Bug#1024870: Scenario in which --extra-suites leads to breakage

["Daniel Richard G." <skunk@iSKUNK.ORG>]

Package: debootstrap
Version: 1.0.128+nmu2

I attempted to bootstrap an Ubuntu jammy system, and got an error:

    $ debootstrap \
        --extra-suites=jammy-security,jammy-updates \
        --force-check-gpg \
        --arch=amd64 \
        jammy \
        test-ubuntu \
        http://local-apt-mirror.example.com/ubuntu
    I: Retrieving InRelease 
    I: Checking Release signature
    I: Valid Release signature (key id F6ECB3762474EDA9D21B7022871920D1991BC93C)
    I: Retrieving Packages 
    [...]
    I: Configuring login...
    I: Configuring libc-bin...
    I: Unpacking the base system...
    W: Failure trying to run: chroot "/tmp/test-ubuntu" dpkg --force-overwrite --force-confold --skip-same-version --install
    W: See /tmp/test-ubuntu/debootstrap/debootstrap.log for details

The last part of the debootstrap.log file:

    [...]
    Unpacking systemd-sysv (249.11-0ubuntu3) ...
    Setting up systemd-sysv (249.11-0ubuntu3) ...
    dpkg: error: --install needs at least one package archive file argument

    Type dpkg --help for help about installing and deinstalling packages [*];
    Use 'apt' or 'aptitude' for user-friendly package management;
    Type dpkg -Dhelp for a list of dpkg debug flag values;
    Type dpkg --force-help for a list of forcing options;
    Type dpkg-deb --help for help about manipulating *.deb files;

    Options marked [*] produce a lot of output - pipe it through 'less' or 'more' !

If I remove the --extra-suites option, the bootstrap completes
successfully.

It appears that the relevant portion of the script is not guarding
against the possibility of an empty package list.
