/usr/bin/unattended-upgrade runs lsb_release:
def init_distro_info():
global DISTRO_CODENAME, DISTRO_DESC, DISTRO_ID
DISTRO_CODENAME = subprocess.check_output(
["lsb_release", "-c", "-s"], universal_newlines=True).strip()
DISTRO_DESC = subprocess.check_output(
["lsb_release", "-d", "-s"], universal_newlines=True).strip()
DISTRO_ID = subprocess.check_output(
["lsb_release", "-i", "-s"], universal_newlines=True).strip()
lsb_release loads info from /etc/os-release or /usr/lib/os-release:
# Load release info from standard identification data files
[ -f /usr/lib/os-release ] && os_release=/usr/lib/os-release
[ -f /etc/os-release ] && os_release=/etc/os-release
[ "${LSB_OS_RELEASE-x}" != "x" ] && [ -f "$LSB_OS_RELEASE" ] &&
os_release="$LSB_OS_RELEASE"
[ "${os_release-x}" != "x" ] && . "$os_release"
This bug is fixed in:
#1115376 - 50unattended-upgrades.Debian is outdated
