Package: cloud-init
Version: 25.1.4-1
Severity: normal
Tags: patch upstream
Dear Maintainer,
On Debian Trixie, cloud-init 25.1.4-1 generates an invalid
deb822-format sources list entry because of a missing newline between
the “Suites” and “Components” fields in the template
`/etc/cloud/templates/sources.list.debian.deb822.tmpl`.a
---
Steps to reproduce:
1. Use a Debian Trixie system with cloud-init 25.1.4 installed.
2. Let cloud-init generate `/etc/apt/sources.list.d/sources.list.deb822`
from the default template.
3. Inspect the resulting file.
Actual result:
Suites: trixie-securityComponents: main non-free-firmware
Expected result:
Suites: trixie-security
Components: main non-free-firmware
Cause:
The jinja template file currently contains:
Suites: {{codename}}{% if codename in ('buster', 'stretch') %}/updates{%
else %}-security{% endif %}
Components: main
Jinja renders this without a newline between the two lines.
Upstream fix:
This issue was fixed upstream in cloud-init 25.2 by commit:
https://github.com/canonical/cloud-init/commit/f21d266eb358b5591128db3b413a72c903cadac1
Please consider backporting this fix or updating to ≥ 25.2.
