Virtualbox Extension Pack Failed To Load The Main Module
frank) (diff) Trying to install Oracle_VM_VirtualBox_Extension_Pack-4.0.4-70112.vbox-extpack I got an error popup saying Failed to install the Extension virtualbox extensions Pack /export/harri/Oracle_VM_VirtualBox_Extension_Pack-4.0.4-70112.vbox-extpack. The installer failed with exit code 127: Error creating textual authentication agent: Error opening current controlling terminal for the process (`/dev/tty'): No such device or address. Details Result Code: NS_ERROR_FAILURE (0x80004005) Component: ExtPackManager Interface: IExtPackManager {2451b1ba-ab1c-42fb-b453-c58433bea8c7} Of course I checked the access permissions to /dev/tty. Its readable and writable for everybody: % ls -al /dev/tty crw-rw-rw- 1 root root 5, 0 Mar 2 06:04 /dev/tty Please note that running Virtualbox as root is not an option. Change History comment:1 Changed 6 years ago by frank Yes, you should never run VBox as root. Therefore the GUI will try to find gksu, kdesudo or just xterm + su to get admin permissions for installing the extension pack. Could you check if some of these requirements are installed? comment:2 Changed 6 years ago by Harri xterm and su are available, but obviously this didn't work. If I try "xterm -e su" on the command line, then a xterm opens, I am asked for the root password, and next I get the expected su session. The bad part on this extension stuff is that it relies upon an XWindow application asking for the root password. Thats _very_ easy to attack, since the password key strokes are sent unencrypted to the server. XWindow wasn't made with security in mind. My suggestion would be to provide the extensions as *.deb files, at least for Debian and Ubuntu. This would make sure that all files are under dpkg control, upgrades could be handled gracef
