[Launchpad Bug Tracker]

This bug was fixed in the package ubuntu-raspi-settings - 24.04.2

---------------
ubuntu-raspi-settings (24.04.2) noble; urgency=medium

  * Removed etc/netplan/01-use-network-manager.yaml: An equivalent is
    now provided under /lib by ubuntu-desktop-settings (LP: #2042866)
  * usr/share/initramfs-tools/hooks/zz-exclude-nvidia: New hook to exclude
    nvidia modules from the raspi initramfs (LP: #2060032)
  * usr/bin/update-v3d-config: Add script and corresponding service to update
    the X11 configuration for Pi 5 displays (LP: #2044718)
  * etc/X11/xorg.conf.d/99-vc4-primary.conf: Renamed to 99-v3d.conf
  * d/ubuntu-raspi-settings-desktop.lintian-overrides: Remove unknown tags,
    add tags for update-v3d-config
  * d/ubuntu-raspi-settings.lintian-overrides: Add override for appstream
    metadata
  * ubuntu-raspi-settings: Removed lz4 dependency; we removed the need for
    this in 24.04.1 when removing the obsolete initramfs-tools hack
  * Remove meson build dependency; dh_install is sufficient

Title:
  Warning: Permissions for /etc/netplan/01-use-network-manager.yaml are
  too open. Netplan configuration should NOT be accessible by others.

Status in ubuntu-raspi-settings package in Ubuntu:
  Fix Released

Bug description:
  This warning is shown in the system journal (during boot):

  nov 06 17:15:23 fpgrpi generate[840]: Permissions for
  /etc/netplan/01-use-network-manager.yaml are too open. Netplan
  configuration should NOT be accessible by others.

  The file /etc/netplan/01-use-network-manager.yaml came from the
  package ubuntu-raspi-settings-desktop and its post install permissions
  are -rw-r--r-- (group and others readable).

  A simple workaround is to remove the file read permission for group
  and others, as suggested, using this command:

  sudo chmod 600 /etc/netplan/01-use-network-manager.yaml
