VirtualBox does not install Guest Additional ISO

I installed almalinux in VirtualBOX in EOS Ganymede, but cannot install additional iso in VM.
I have installed virtualbox-iso package and Almalinux display iso in VM.

But when I click “Install additional iso“ in the menu of Virtualbox when VM running, Virtualbox don`t react to this. I still can use Vm, but this button “Install additional iso“ do nothing.

Could you share a screenshot of what you mean (I can’t use a VM on my current system so I can’t open it to see) and I will try to help you out (and if I can’t there is a good chance people will give you some ideas at to at least look at alongside the info you already shared)

I It does not reaching to this, even if I login

Silly question. Do you have the iso mounted?

Yes

Not sure but something in my head is saying this isn’t what it’s for, I could be really wrong but might be worth checking out

Yeah, you could try looking for a install guest additions option within the actual distro or failing that, run virtualbox from the terminal and see if you get any errors showing up. . Of course, it may be a bug.

In the shell i see only this:
Qt WARNING: QObject::disconnect: wildcard call disconnects from destroyed signal of UIInvisibleWindow::unnamed

Hmm it seems to be killing some process possibly the one needed in this case but the message is quite vague

I had to download the guest addition iso into almalinux downloads folder then mount it and open a terminal and ls into the file. From there there is an install.sh that installed it into almalinux.here is the link to the ios from virtualbox.

https://download.virtualbox.org/virtualbox/7.2.6/

Now work, try to install now

I ran into the same issue trying to use virtualbox to install the guest additions.I do not know if it is a bug or security issue.Using the iso from inside almalinux worked for me.I have also installed the additions the same way with arch as well.

Failed

(VERR_PDM_MEDIA_LOCKED).(VERR_PDM_MEDIA_LOCKED).

Why would you do that when you can install the Arch package :
sudo pacman -S virtualbox-guest-iso

As i understood the OP they can not get the guest additions to work with EOS virtualbox running almalinux as a guest.The guest addictions are installed in EOS.I may have misunderstood the OP.

That’s as I understood it @straycat, but perhaps I misunderstood too.

I’m curious to hear from @vazicebon whether there’s a next step, in making the installed virtualbox-guest-iso available to a non-Arch guest.

@wodsfortdragon, to build on what vazicebon said: while you need the ISO on the host, the actual installation must happen inside the Guest VM. Since your guest is AlmaLinux (not Arch-based), the process for installing dependencies and running the installer is specific to that distro. Because this is a guest-side configuration issue for a non-EndeavourOS system, you’ll likely find better step-by-step help in the AlmaLinux or VirtualBox forums. Good luck!

As I posted earlier I downloaded the iso from virtualbox into the downloads folder in almalinux

I used gnomedisks to mount the iso.

The iso was mounted in /run/media/username/isoname

cd to that in a terminal

ls in terminal showed the contents of the ios.

sudo ./autoinstall.sh I am pretty sure is the right name if not it is close.

that installed the additions

They might also make sure kernel-devel is installed as well

If using fedora as a guest it is already installed in the guest.Red Hat based it is not.

Feel free to correct as mistakes as my memory is not what it used to be.
