Thanks for your answer but as I told you, I already tried removing the comma from line 7 in the menu.json.
I tried package helper2-1.0.1 with this menu.json (removed trailing comma from line 7)

{
    "items": [
        {
        "name": "Helper",
        "priority": 0,
        "items": [
            {"name": "Set DateTime from Server", "priority": 1, "action": "bin/ntpdate.sh"}
        ]
        }
    ]
}

However I don't get the entry to show in KUAL.
Then I tried the same package with the menu.json from the new repo:

{
    "items": [
        {
        "name": "DateTime",
        "priority": 0,
        "items": [
            {"name": "Set DateTime from Server", "priority": 0, "action": "bin/ntpdate.sh"}
        ]
        }
    ]
}

But this didn't work either.
The last thing I tried was copy the whole ntpdate folder from the new repo to the extensions directory.
Unfortunately, that also didn't lead to any success.

Also the KUAL.log under /tmp is empty. How can I look into the KUAL.log and where is it located?

Thanks and best regards!
