Bug#989724: debootstrap: `--extra-suites=A,B` not showing up in `/etc/apt/sources.list`

[Paul Menzel <pmenzel@molgen.mpg.de>]

Package: debootstrap
Version: 1.0.123
Severity: normal


Dear Debian folks,


Ubuntu uses several suites for installations, but adding these with 
`--extra-suites=`

    sudo /usr/sbin/debootstrap --arch=amd64 --keyring 
/scratch/tmp/ubuntu-archive-keyring.gpg 
--extra-suites=focal-updates,focal-security focal ./focal-chroot

does not work.

    $ grep -R focal focal-chroot/etc/apt/
    focal-chroot/etc/apt/sources.list:deb 
http://archive.ubuntu.com/ubuntu focal main


Kind regards,

Paul
