vagrant - cannot get up minidcos with docker and DCOS OSS release 2.2.2; followed official minidcos install/setup routine w/ no success

Question

I try to get up and run a small dev-cluster for DCOS with latest stable release.
For this, I followed official minidcos routine here:
https://minidcos.readthedocs.io/en/latest/dcos-docker-cli.html#minidcos-docker and ran the following:
minidcos docker create --variant oss --no-enable-spinner /home/debian/Downloads/dcos_generate_config.sh --agents 1
I succeed til that point where I have to wait til cluster is up and ready:
minidcos docker wait --cluster-id default (at this point spinner is activated)
At this point the spinner turns and turns and turns without any feedback that/if the small cluster is ready to use or not. But, with 'top' (as the only way I know to get information at this time) I see there is no more 'tar xf' running, so in my eyes the cluster should be ready, but does not show the hint on logging on its IP address.
(should be something like 172.17.0.2/8)
Also tried to log onto this IP address and got the known login screen with DCOS logo, after entering login information, the next window shows that I am directly logged out, so no login possible here.

I tried the docker and also the vagrant (w/ Virtualbox) way.
On the vagrant way, lxc is used as 'provider', which is installed but cannot be used/accessed, as an additional error message shows:
Name: mesosphere/dcos-centos-virtualbox
Address: https://downloads.dcos.io/dcos-vagrant/metadata.json
Requested provider: [:lxc] ...
The box you're attempting to add doesn't support the provider you requested. Please find an alternate box or use an alternate provider. Double-check your requested provider to verify you didn't simply misspell it.

OS: Debian Buster w/4.19.X latest kernel
Docker: Docker version 20.10.1, build 831ebea
Vagrant: Vagrant 2.2.3
VBox: Version 6.1.16 r140961 (Qt5.11.3) plus extensions installed
Conda: conda 4.9.2

Does somebody have a clue on this? I am stuck and also skrewed up since a former/earlier version was to be set up smoothly and running painlessly, but it is not possible to use this elder version.
Any help in this will be highly appreciated, since I do not know which information may be needed for you to support, pls ask which one you need from my system.
I will try to provide them as detailed as possible.

Thanks to all and regards,
Roger
