Segmentation fault in postinst script #744
Description
Hi,
we have a problem using iot hub device update with Debian 12 on armhf. We built it from source because there is no package provided. Then the .deb file was extracted and installed on the target system. That package additionally requested delivery optimization which was also build from source and then installed succesfully. Intalling deviceupdate-agent now fails in the postinst script.
Expected Behavior
Normal adu agent installation and operation.
Current Behavior
Fails with segmentation fault when running postinst script.
Steps to Reproduce
- Build for Debian 12 armhf (we tried docker with qemu emulation, raspberry pi5 running raspbian32 bit and also compiling on our target device stm32mp1 based)
- Extract .deb package
- Try install
Device Information
- Host OS [Debian12]:
- Architecture [arm32]:
- Provisioning Method: Iot Edge (ais)
*DU Agent Version : 1.2.0

We allready tried commenting parts of the postinst script but the behaviour is the same for all extensions also when excetued seperatly from the install script.
