How can I force the installation of the Virtualbox Extension pack?

Question

I have a BIG problem with VirtualBox; every time I try to add or install the newest extension pack, it gives an error; at first, it asked me to add my user to the vboxuser group, which I already did, but still can't install the extensions pack.

How can I force Virtualbox to install it?

It says, Failed to install extension pack—the path to the file, and the error itself.

Here I tried running it on the root terminal, but Virtualbox crashes.

 uri-MS-7267 uri # virtualbox
 Qt CRITICAL: Qt-subapplication(20282)/kdeui (KIconLoader): Error: standard icon theme "oxygen" not found! 

 Qt WARNING: QPainter::begin: Paint device returned engine == 0, type: 3

 Qt WARNING: QPainter::begin: Paint device returned engine == 0, type: 3

 Segementation fault

When trying to install the Extpack from the terminal i get this:

 uri@uri-MS-7267 ~ $ sudo VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.0.10- 72436.vbox-extpack
 0%...
 Progress state: NS_ERROR_FAILURE
 VBoxManage: error: Failed to install "/home/uri/Oracle_VM_VirtualBox_Extension_Pack-  4.0.10-72436.vbox-extpack": The installer failed with exit code 1: VBoxExtPackHelperApp:   error: The owner is not root: '/usr/lib'

And I get nothing when using gksu.

 uri@uri-MS-7267 ~ $ gksu VBoxManage extpack install Oracle_VM_VirtualBox_Extension_Pack-4.0.10-72436.vbox-extpack
 uri@uri-MS-7267 ~ $ 

Solution 1

You can try to install the extension pack using the command line:

sudo VBoxManage extpack install <package file>

Some random things to check:

• Virtualbox version and extension pack version must match.
• Files on /usr/lib/virtualbox must be owned by root.
• /usr/lib itself must be owned by root, too as Uri himself find.

Solution 2

It seems to be saying you need to be root, so run it as root, and then install the pack.

It crashes when i run it with gksu or plain sudo, with QT warnings about me not having the oxygen theme (?).

[Jason Southwell]

@Uri you should probably report a bug O.o

[Uri Herrera]

i also tried with gksu and the command you suggested, i get no errors in return but, the extension pack doesn't show as installed.

[Uri Herrera]

Where do i report it?

[Jason Southwell]

@Uri I'm not sure where they track their bugs.

I added some blind shots, maybe one of them works.

[Uri Herrera]

I've downloaded the previous version 4.0.8.7.1778 of both the Vbox deb and the ext pack, i've installed the deb and attempted to install the Extpack, and i still get the same error. :(

[Uri Herrera]

I also checked with PCMANFM the permissions of /usr/lib/virtualbox and it says root.

[Uri Herrera]

usr/lib/ however says, the owner is my user, should it be like that?.

[Uri Herrera]

Looking at my netbook /usr/lib is owned by root :O, i don't know how or why that happened >.<.

[Uri Herrera]

Just fixed it, changed it's owner, thanks for the hints :)

[Javier Rivera]

BTW, that was exactly what the error message was saying all this time... LOL.

[Uri Herrera]

Yeah, now i get it... >_< haha facepalm
