Maui 17.3 : Dolphin star rating for pictures is not saved

[benit]

well.. I have Maui installed bare metal, not in a virtual machine. Within Maui I use vmware for a few Windows programs.

So how should I remove virtualbox-guest-* packages?

Simply type "sudo apt-get remove virtualbox-guest-* " in a command line?

And what about the system info page?

At least via "plasmashell --version
" I could find out that indeed I have updated to Plasma 5.10.2

So I would like to figure out the rest.
