virtualbox.org

Hey guys,

once there came up a update notification telling me there is a new version for virtualbox I may wanna download and install, so I did. I ran the downloaded package and proceeded as the graphic interface told me. He actually did some processing, but finally told me 'The installation failed. The Installer encountered an error that caused the installation to fail. Contact the software manufacturer for assitance.'

Okay, I tried the update process again several times with different circumstances, such as after a fresh reboot and so on ... but again, the update failed.

Next try was to remove virtualbox completely and do a fresh install. But there I'm stuck again, I can't even uninstall virtualbox, when I run the uninstall tool, the following happens in my console:

Do you wish to uninstall VirtualBox (Yes/No)?
Yes

The uninstallation processes requires administrative privileges
because some of the installed files cannot be removed by a normal
user. You may be prompted for your password now...

sudo: /etc/sudoers is mode 0646, should be 0440
/Volumes/VirtualBox/VirtualBox_Uninstall.tool: line 195: 631 Segmentation fault /usr/bin/sudo -p "Please enter %u's password:" /bin/rm -Rf $my_files $my_directories
An error occurred durning 'sudo rm', there should be a message above. (rc=139)

The uninstall failed. Please retry.
logout

[Process completed]

I then once again ran this tool as 'root', but no success there either.

I'd really appreciate your help, thanks!
