Virtualbox leap 15.6 ; 2025 aug

[maliei]

installed leap 15.6, try to install virtualbox, start VB => message pop up:
You are not a member of the “vboxusers” group. Please add yourself to this group before starting VirtualBox. You could do it using: Yast / Security and Users / User and Group management. Don’t forget re-login your user account!

1. Iam 75 year old, above message tells me nothing!
2. Is there anyone knowledgeable who can explain exactly what I should do.
3. Please be detailed. Thanks!

Open Yast----Security and User—User and Groups

mark your User----klick on edit-------Details

on the right side scroll down for vboxusers and mark it—ok----ok

Now logout on KDE/Gnome and login.

This is from a German openSUSE, so it might be other descriptions.

You can also do it in Terminal by:

sudo usermod -a -G vboxusers YOURUSERNAME

YOURUSERNAME must be replaced by your real Username in openSUSE.
For me it is
stephan, see the userprompt when opening a User terminal:

stephan@linux64:~> 

[Sauerland]

For both:
Relogin is important, otherwise it will not work

Many Thanks! It works! Have a nice day!

First, welcome to the openSUSE Forums.

My age is 3/4 of 100 years + 1 year …

• And, the above messages mean an awful amount to me due to the fact that –
  My first contact with UNIX® was in the mid-1980’s and, other multi-user Operating Systems before that …

Please be aware that, Linux is a UNIX® and, UNIX® is a multi-user Operating System –

• As is, Android – also a Linux …
• As is Apple macOS – a Berkeley Software Distribution UNIX® variant.

As a multi-user OS Linux, like all the other UNIX® variants, has multiple users and, user groups.

• Each user is assigned a UID – User Identification – an integer number.
• Each user is also assigned a GID – Group Identification – also an integer number.
• Each user can also be a member of any of the Groups defined on any given system.

Why?

• In a multi-user system, the users are either human beings or, part of the Operating System.
• And, the system’s users can be organised into groups – where each Group is assigned a specific task –
  The human users may be members of specific company departments – where each department performs specific tasks within the company.
  The system users may be involved with specific system tasks which need to be separated from one another by means of groups.

In the case of the Oracle VirtualBox product, only specific users are allowed to create and use Virtual Machines – those who are members of the “vboxusers” Group.

The same applies to network protocol analysers such as “Wireshark” – only users who are members of the “wireshark” group are allowed to inspect the data streams entering and leaving the system’s network interfaces.
