Error when installing extension

Hi,

When trying to install the VM Insights, the AzureMonitorLinuxAgent extension gets stuck in "transitioning" state.

Under details I can see the following message:

`[ExtensionOperationError] Non-zero exit code: 127, /var/lib/waagent/Microsoft.Azure.Monitor.AzureMonitorLinuxAgent-1.6.2/./shim.sh -enable [stdout] 2021/03/09 20:27:17 [Microsoft.Azure.Monitor.AzureMonitorLinuxAgent-1.6.2] Enable,failed,127,Enable failed with exit code 127 /bin/sh: 1: /etc/init.d/mdsd: not found [stderr] Running scope as unit: Microsoft.Azure.Monitor.AzureMonitorLinuxAgent_1.6.2_45ed8970-ede5-4fcb-908c-79ae6d9819b3.scope /bin/sh: 1: /etc/init.d/mdsd: not found
`

when trying to find install the azure-mdsd package from apt repo, I receive the following message:

```
apt install azure-mdsd
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package azure-mdsd is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'azure-mdsd' has no installation candidate

```

Any help please?

Many thanks and best regards,
