Hi everyone,

I am new to this Linux environment, so it is quite challenging to understand what is happening while installing things. I tried to install VirtualBox using command lines. I followed the steps described in a tutorial https://pupli.net/2019/08/install-virtualbox-on-kde-neon-ubuntu-18-04/ , but they didn't go through.
I some point I finally typed :

Code: Select all

sudo apt install virtualbox-6.0

It does :

Code: Select all

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
 virtualbox-6.0 : Depends: libvpx5 (>= 1.6.0) but it is not installable
                  Recommends: libsdl-ttf2.0-0 but it is not going to be installed
E: Unable to correct problems, you have held broken packages.


Do you know how I could "fix" my broken packages?

Thanks in advance,

Those instructions may be old, for *buntu 18.04. Instructions for Ubuntu 20.04 will work here, as this is what KDE neon is.
You probably can fix this by editing the repo info you added

Open /etc/apt/sources.list with kate/kwrite, and edit the lines, replacing 'bionic' with 'focal' which will point things to the Ubuntu 20.04 (Focal) compatible packages.

Then save, update, and try again, though install virtualbox-6.1 instead, which is much more current.

Hi Claydoh, thanks for the fast and efficient answer!
I did everything you wrote and it worked perfectly. I have another error now, but within VB a window pops up with the following message:

Code: Select all

Kernel driver not installed (rc=-1908)

The VirtualBox Linux kernel driver is either not loaded or not set up correctly. Please try setting it up again by executing
'/sbin/vboxconfig'
as root.
If your system has EFI Secure Boot enabled you may also need to sign the kernel modules (vboxdrv, vboxnetflt, vboxnetadp, vboxpci) before you can load them. Please see your Linux system's documentation for more information.
where: suplibOsInit what: 3 VERR_VM_DRIVER_NOT_INSTALLED (-1908) - The support driver is not installed. On linux, open returned ENOENT.

I don't know what it means yet, but it's another topic I guess, so I'll check that a bit deeper. (If you have an idea, you are very welcome though )

Thanks again.

The messaging tells you exactly what to do , at least to start. Run that command. You *might* need to reboot afterward.
Otherwise, you *may* also have to disable secure boot in your bios if you still get similar messages (easier than signing things)

Hi,

I tried /sbin/vboxconfig before, it does

Code: Select all

rm: cannot remove '/sbin/rcvboxdrv': Permission denied
ln: failed to create symbolic link '/sbin/rcvboxdrv': File exists
/sbin/vboxconfig: 155: cannot create /lib/systemd/system/vboxdrv.service: Permission denied

ln: failed to create symbolic link '/sbin/rcvboxweb-service': File exists
/sbin/vboxconfig: 155: cannot create /lib/systemd/system/vboxweb-service.service: Permission denied

What did you mean by reboot/disable secure boot?

Also, you actually fixed my initial problem, should I close this topic, and open a new one?

Thanks in advance,

Renaud

"Permission denied" means you need to use sudo when running the original /sbin/vboxconfig command, as you need elevated (admin) privileges in order to do this operation.

After successfully running the command, you *might* have to reboot for it to start working, I am not sure if it does. It has been ages since I have used VB.

As to secure boot, that is a setting in your bios, that you potentially need to switch off, if it still does not work.

In your computer's firmware/BIOS/UEFI, make sure that all hardware virtualization technologies available for your computer are enabled: Intel VT-x, Intel VT-d, AMD AMD-V, AMD-Vi, other (EPT, RVI, VMCS shadowing, GVT, SR-IOV etc.). If it is available and you can enable it, then enable it.

Arch/Manjaro: sudo pacman -S virtualbox
Fedora: sudo dnf install VirtualBox
KDE Neon/Kubuntu/Ubuntu/Debian: sudo apt install virtualbox
openSUSE Leap & Tumbleweed: sudo zypper install virtualbox
macOS: brew install virtualbox
Windows: https://virtualbox.org/wiki/Downloads

Once VirtualBox is installed, launch it.
