I'm on the latest official release for my platform (azure-cli-2.37.0-1.el7.x86_64) which has not changed, so the output is still the same (as is to be expected). To reproduce:

$ az extension remove -n ssh
$ az network bastion ssh --username xxx --auth-type ssh-key --ssh-key ~/.ssh/id_rsa --resource-group bastion-rg --name bastion --target-resource-id "/subscriptions/xxx/resourceGroups/xxx/providers/Microsoft.Compute/virtualMachines/xxx-vm"

This gives a lot of output (namely, a python stack trace) and this message: "The command failed with an unexpected error."

The expected behaviour would be:

1. show me how the ssh extension can be installed
2. do not throw an "unexpected error"

This also has not changed. BTW I never said I was "facing the issue" I just wanted to provide you with feedback to improve the user experience. All I have to do is install the ssh-extension, and I can work with "az network bastion ssh ..".
