ExtPack installation failure

[D-H]

I have VirtualBox running as an unprivileged user on a RHEL 7.4 server with no GUI, phpvirtualbox is installed on this machine. I've recently upgraded to 5.1.26 and I'm trying to install the extension pack so I have console access to my VMs which are mostly used as build machines.

Trying to install as the unprivileged user gives the following error:

vbox@virthost:~$ vboxmanage extpack install ~/Oracle_VM_VirtualBox_Extension_Pack-5.1.26-117224.vbox-extpack --accept-license=715c7246dc0f779ceab39446812362b2f9bf64a55ed5d3a905f053cfab36da9e

vbox@virthost:~$ 

It is possible to install the extpack as root or with sudo but this only makes the extensions available for root and not as the unprivileged user that is running the VMs.

Sorry, but installing the Extension Pack as root does NOT restrict the Extension Pack for unprivileged users. So running

sudo VBoxManage extpack install ...

should fix your problem.

Hi Frank,

I can install OK as root or using sudo

vbox@virthost:~$ sudo vboxmanage extpack install ./Oracle_VM_VirtualBox_Extension_Pack-5.1.26-117224.vbox-extpack --accept-license=715c7246dc0f779ceab39446812362b2f9bf64a55ed5d3a905f053cfab36da9e

But the extpack is not available to the unprivileged user.

vbox@virthost:~$ vboxmanage list extpacks
Extension Packs: 0

It's only available to root

vbox@virthost:~$ sudo vboxmanage list extpacks

Hmm, that used to work! Which VirtualBox package (exact name please) are you using?

[D-H]

VirtualBox-5.1-5.1.26_117224_el7-1.x86_64.rpm
Oracle_VM_VirtualBox_Extension_Pack-5.1.26-117224.vbox-extpack

[maico]

add root permission

Hi Maico, Has this change been included in any releases yet?

Thanks.

Hi Maico. This issue is still marked new.

It also still fails in VB 6.1.26 on final Centos 6.

Was any resolution found?

Hi klydar,

Have you tried the latest official release 6.1.26 (https://www.virtualbox.org/wiki/Linux_Downloads)? I do not see the issue with it.

Hi, I had the exact same problem too, so found here. I am using VB 6.1.34 r150636, Manjaro 5.15.48.

I solved the problem by doing another install under the normal user, it seems that the normal user and root permissions were fixed by coincidence in this install.

~ vboxmanage extpack install Oracle_VM_VirtualBox_Extension_Pack-6.1.34.vbox-extpack
...
...
VBoxManage: error: Extension pack 'Oracle VM VirtualBox Extension Pack' is already installed. In case of a reinstallation, please uninstall it first
VBoxManage: error: Details: code NS_ERROR_FAILURE (0x80004005), component ExtPackManagerWrap, interface IExtPackManager

then you can list it

~ vboxmanage list extpacks

Hi guys,

I do not see the issue with VirtualBox 6.1.36. Extension Pack can be installed either with "sudo VBoxManage extpack install.." or without involving sudo. In the second case, your Linux distribution is expected to have installed either kdesudo, gksu, pkexec or su tool for Extension Pack installer to ask root password.

In both cases, "VBoxManage list extpacks" is showing installed Extension Pack as a result.

klydar, I am also able to install extpack 6.1.36 into ContOS 6.6. I assume this issue was fixed long time ago. Closing it.
