Azure VM Backup pre_post igored on Ubtuntu 22.04 LTS

we setup pre_post like described here: https://learn.microsoft.com/de-de/azure/backup/backup-azure-linux-app-consistent

but it seems ignored during backup

# cat /etc/azure/VMSnapshotScriptPluginConfig.json
{
    "pluginName" : "ScriptRunner",
    "preScriptLocation" : "/root/consisten-azure-vm-backup/stop-icinga_services.sh",
    "postScriptLocation" : "/root/consisten-azure-vm-backup/start-icinga_services.sh",
    "preScriptParams" : ["", ""],
    "postScriptParams" : ["", ""],
    "preScriptNoOfRetries" : 0,
    "postScriptNoOfRetries" : 0,
    "timeoutInSeconds" : 30,
    "continueBackupOnFailure" : true,
    "fsFreezeEnabled" : true
}
#

Maybe the problem is:

platform.dist() was removed in phyton 3.7 see https://docs.python.org/3.5/library/platform.html#platform.dist

see also similar issue: https://github.com/psychopy/psychopy/issues/2733

current versions:

# waagent --version

It seems no APP consistent backup currently possible with the provided agent Features. Also we cannot use database consistent backup because Application crashes when DB is set to read only.

For me a non consistent Backup is useless.
