Issues installing IOT Edge on a Raspberry PI 4 running Ubuntu 22.04 Desktop

Hi. I am trying to install IOT Edge on a Raspberry PI 4 running Ubuntu 22.04 Desktop but I am having issues…

I followed the instructions outlined on this page:

https://learn.microsoft.com/en-us/azure/iot-edge/how-to-provision-single-device-linux-symmetric?view=iotedge-1.4&tabs=azure-portal%2Cubuntu

dave@piu:~$ sudo apt-get install aziot-edge

Some packages could not be installed. This may mean that you have

requested an impossible situation or if you are using the unstable

distribution that some required packages have not yet been created

or been moved out of Incoming.

The following information may help to resolve the situation:

The following packages have unmet dependencies:

 aziot-identity-service : Depends: libssl1.1 (>= 1.1.0g) but it is not installable

                                          Depends: libtss2-esys0 (>= 2.3.1) but it is not installable

E: Unable to correct problems, you have held broken packages.

This page: https://learn.microsoft.com/en-us/azure/iot-edge/support?view=iotedge-1.4

… states that Ubuntu 22.04 Server on ARM is a Tier 1 supported platform.

Is my problem simply that Ubuntu Server is supported but Ubuntu Desktop is not?

Or is it to do with the SSL stuff?

When I run 'apt list --installed' these packages are in the list…

   libssl3/jammy-updates,jammy-security,now 3.0.2-0ubuntu1.15 arm64 [installed,automatic]

   libtss2-esys-3.0.2-0/jammy,now 3.2.0-1ubuntu1 arm64 [installed,automatic]

   libtss2-mu0/jammy,now 3.2.0-1ubuntu1 arm64 [installed,automatic]

   libtss2-sys1/jammy,now 3.2.0-1ubuntu1 arm64 [installed,automatic]

   libtss2-tcti-swtpm0/jammy,now 3.2.0-1ubuntu1 arm64 [installed,automatic]

   ssl-cert/jammy,now 1.1.2 all [installed,automatic]

Any assistance would be greatly appreciated.

Thanks, Dave
