Package: cdimage.debian.org
Severity: important
X-Debbugs-Cc: debian-live@lists.debian.org

Found in testing of the 12.7.0 live images.

Doing a live installation using calamares from either of these images
fails if no network is available.

Running /usr/sbin/bootloader-config fails to install the appropriate
grub packages and times out after 600 seconds.

Sequence of issues:

1. /etc/apt/sources.list for the image has deb.debian.org listed above
   the on-media packages. Has that changed in live-build?
2. Connman is running a DNS server on 127.0.0.1, which apt uses to
   look up deb.debian.org
3. That DNS server does not fail if no network is available. Instead,
   it hangs.

The bootloader-config script eventually times out and the installation
fails.

The workaround is to configure networking and then things work, but
offline installation is an important thing for some people.
