The armhf .deb on PMC is for armv7+ only, so would need to recompile for armv6l I think with -mcpu, etc. We support gen2+ not gen1 cortex cpu I think, so RPi3B+ is supported but RPi Zero.
Error 132 is likely errno EOVERFLOW and for ARMv7/armhf so my guess is it is using an instruction that is not available on armv6l.
The key issue I am seeing is the binary has armv7-only mov.w instruction in the _startup function in the ELF binary that are instructions not available in armv6l
wget https://packages.microsoft.com/debian/11/prod/pool/main/d/deviceupdate-agent/deviceupdate-agent_1.1.0_armhf.deb
ar x deviceupdate-agent_1.1.0_armhf.deb
tar xzvf data.tar.gz
sudo apt install -y gcc-arm-none-eabi
arm-linux-gnueabihf-objdump -d ./usr/bin/AducIotAgent > out.log
grep '<_start>' out.log -B4 -A 5Here is _startup with the armv7-only mov.w instruction:
0000e17c <_start>:
e17c: f04f 0b00 mov.w fp, #0
e180: f04f 0e00 mov.w lr, #0
e184: bc02 pop {r1}
e186: 466a mov r2, sp
e188: b404 push {r2}readelf -A ./usr/bin/AducIotAgent shows it is compiled as armv7 so could have instructions in a .o that is not available in armv6l arch

Expected Behavior
Working device update agent to perform multi-step update.
Current Behavior
If I try to install the deviceUpdate-agent with command: sudo apt-get install deviceupdate-agent I am getting error: Register all reference step handlers... /var/lib/dpkg/info/deviceupdate-agent.postinst: line 218: 10000 Illegal instruction $adu_bin_path -l 2 --extension-type updateContentHandler --extension-id "microsoft/apt:1" --register-extension $adu_extensions_sources_dir/$adu_apt_handler_file dpkg: error processing package deviceupdate-agent (--configure): installed deviceupdate-agent package post-installation script subprocess returned error exit status 132 Processing triggers for man-db (2.9.4-2) ...
