QNAP, trial: No packages...?

[Django2020]

Hi there,
very new to minimserver.

minimserver is installed, see image (2.0.12 update 162, using MinimServer-2.0.12-armv5.qpkg on a QNAP TS412, firmware 4.3.3.0644 - yes, very old).

I believed there should be another menu, showing Packages or something (I'm particularly interested in minimstreamer). But the page looks exactly as before activating trial (yes, minimserver was restarted).
minimserver is a tab on Firefox; shouldn't minimserver be a window/app on the QNAP-GUI?
JRE 8.151.2 is installed.
The profile just shows the path, which has been indexed (as I can see from the logs with zillions of errors).

minimserver-sh.log shows
/usr/local/nptl not found (no other errors).

What am I missing?

Cheers,
D.
