Package: raspi-firmware Version: 1.20200601-2 Severity: important /etc/kernel/postinst.d/z50-raspi-firmware will fail in the following situations:
1) findmnt fails. It attempts to mitigate this:
ROOTPART=`findmnt -n --output=source /`
if [ -z "$ROOTPART" ]; then ROOTPART=/dev/mmcblk0p2;fi
But findmnt will exit 1 and fail -e, so this is needed:
ROOTPART=`findmnt -n --output=source / || true`
if [ -z "$ROOTPART" ]; then ROOTPART=/dev/mmcblk0p2;fi
2) dtbs don't exist for kernel being considered:
for dtb in ${dtb_path}/bcm*.dtb; do
[ -e "${dtb}" ] && cp "${dtb}" /boot/firmware/
[ will exit 1 in that case and fail -e, so we need to flip the test:
for dtb in ${dtb_path}/bcm*.dtb; do
[ -e "${dtb}" ] || continue
cp "${dtb}" /boot/firmware/
Context: live-build pulls in all packages which have files in
/lib/firmware, so raspi-firmware is installed in the arm64/armel chroot
it's building, even though it's not necessarily targeting raspi hardware
or kernel.
Thank you!
