First of all I want to thank you for the real great VirtualBox-Guide here. It's a pity that VirtualBox is not anymore in the Debian 10 repo.
With your how-to it was easy to install. Thanks again.
There's still one issue I had.
After I did all the steps in the guide I wanted to log in the web interface (IP-Server:8080) but neither with the vbox user nor with phpvirtualbox-webgui user I couldn't log in. I always got the info that user/password is incorrect.
So I was looking around in the www and found a hint to use admin/admin for user/password. With that I could log into the GUI.
Why it is like that? Did I something wrong or is this correct to use admin/admin.
Till now I didn't have time to create a VM. First I want to be sure that the basic stuff is running without any issues.
Thanks in advance
