OMV4 - no information about updates in WebGui available

Hello,
my OMV system sends regularly informations about new available updates to my set up email adress. So far thats working perfect. But since a while, I can't see any of the propagated updates in my web gui. If I do a check in the system update Gui there's nothing showing up.
So I wonder if something is misconfigured in the process, and why this happens. Before, I was shown the relevant updates in this web gui and could activate/trigger them from there.

Actual example and screenshots attached (i.e. information which I got by email...).

Any ideas, experiences about this behaviour? Thanks a lot in advance!

Hi Adoby,
thanks a lot for your answer!

Yes, my system is up with a valid acces to the internet (cheked it by a ssh and apt-get update comand), so thats not the problem.

I got this... please have a look in my screeenshot. Looks like sth is wrong in some other settings, but no shure if that's influencing the descibed GUI behaviour.

As I can remember old OMV version, all updates were shown in the systems update gui.

Thanks, I know mc (even not so familiar by its components...).

I've rechecked my received system-infos again - one update from the jan-14th just downloaded the data in "download only" mode (see scrnshot) and another one, from jan-15th actually stated the update process itself (scrnshot).

In my opinion, thats little bit strange, I expected the system to do nothing with the first downloaded data (from the 14th) since it said "in download only" mode . But - even without my interaction - on the 15th those update data were really processed. Didn't expect this to be done automatically !

So, may be everathing is updated and system is in good state. (?)
