  • Bug#1110240: cloud-init: generates apt sources referencing the defunct

    From Noah Meyerhans@21:1/5 to All on Fri Aug 1 20:30:02 2025
    Source: cloud-init
    Version: 20.4.1-2+deb11u1
    Severity: important

    Cloud-init has the ability to generate apt sources when provisioning a system. It does this based on a template installed at /etc/cloud/templates/sources.list.debian.tmpl. The template currently in bullseye results in an incorrect sources.list configuration for a couple of reasons:

    1. The security repository is incorrect, resulting in a system that's not
    configured to install security updates by default.
    2. The bullseye-backports repository is enabled by default, but it no longer
    exists.
