Azure Sphere SDK installation fails on Linux due to missing Libssl3 replaced by libssl3t64

Question

Hi,

Has anyone figured out how to install the AZ Sphere SDK on a fresh install of Ubuntu 24.04. LTS?

Here's what is happening. azure_sphere_sdk_2403.sh launches fine and starts install. Stops with error that libssl3 can't be found.

I APT install the library but ubuntu 24.04. Replaces libssl3 with a newer flavour libssl3t64.

I relaunch the azure_sphere_sdk_2403 with no luck. Same message; can't find the libssl3 although libssl3t64 is installed...

Is it possible to down grade to libssl3?

Thank you for your support

Hello,

Thank you for posting the question.

Ubuntu 24.04 is currently not supported on Azure Sphere SDK 24.03 or earlier. It will be fully supported in the next release of the SDK.

As a workaround, for the Ubuntu 24.04 LTS:

1. Replace lines 350+ in the existing Azure Sphere (public) installer.

if [[ $lsb_release == "22.04" || $lsb_release == "24.04" ]]
	then
	   DEPENDENCIES=(
	   "libssl3"
	   "libc6"
	   "libgcc-s1"
	   "libstdc++6"
	   )
	else
	   DEPENDENCIES=(
	   "libssl1.1"
	   "libc6"
	   "libgcc-s1"
	   "libstdc++6"
	   )
	fi
	
	with the following...
	
	DEPENDENCIES=(
	"libc6"
	"libgcc-s1"
	"libstdc++6"
	)
	
	if [[ $lsb_release == "22.04" ]]; then
	   DEPENDENCIES+=("libssl3")
	elif [[ $lsb_release == "24.04" ]]; then
	   DEPENDENCIES+=("libssl3t64")
	else
	   DEPENDENCIES+=(
	   "libssl1.1"
	   )
	fi

Note: This is only a workaround, and you may still face some problems. Please ensure that you update the SDK when the next release is available.
