The CLI gives the following error when trying with the following command: {{{ VBoxManage extpack uninstall ""Oracle VM VirtualBox Extension Pack"" 0%... Progress state: NS_ERROR_FAILURE VBoxManage: error: Failed to uninstall ""Oracle VM VirtualBox Extension Pack"": The installer failed with exit code 127: Error executing command as another user: No authentication agent was found. }}} The GUI shows the same error. Same thing happens when trying to install the ExtPack. One was able to upgrade the ExtPack on 4.0.0 (when the beta ExtPack was installed for example). I had to use sudo to install the ExtPack. Please revise 4.0.2 ASAP so the forum isn't filled with this problem." defect closed other VirtualBox 4.0.2 fixed other Linux
