Thread: VirtualBox fails to start with error Effective UID is not root

  1. #1

    Default VirtualBox fails to start with error Effective UID is not root

    VirtualBox fails to start. Was working previously, so an update somewhere has hosed it.

    Error message with title "VirtualBox - Error in SUPR3HardenedMain"

    Code:
    Effective UID is not root (euid=1000 egid=100 uid=1000 gid=100) (rc=-10)
    
    Please try reinstalling VirtualBox.
    
    where: SUPR3HardenedMain what: 2 VERR_PERMISSION_DENIED (-10) - Permission denied.
    The suggestion to "...try reinstalling VirtualBox" does nothing.

    This indicates a problem with the file permissions.
    I suppose it will work fine run as root (via kdesu or "su -" e.g.), right?

    What security level are you using?
    Code:
    grep SECURITY /etc/sysconfig/security
    What permissions do the installed files have?
    Code:
    ls -l /usr/lib/virtualbox/
    (note that I assume you are using the openSUSE package here, I'm not sure whether things/locations are exactly the same in Oracle's package)

    That's fine.
    If it had been set to "secure" or "paranoid", your problem would have to be expected because then users are not allowed to run VirtualBox at all because of the stricter permissions.

    As expected, the file permissions are wrong.
    The marked files should have the suid bit set. You can set it manually (chmod +s filename), or better run "chkstat --system" to fix all wrong file permissions.
    If the latter prints errors, please post them for further help.

    Correct. Update from official repos self-hosed itself.
    Never had a problem here, on two different systems.

    Just because someone else had a similar problem doesn't necessarily mean there's a bug somewhere.

    run "chkstat --system" to fix all wrong file permissions
    Worked.

    Here are some more letters to make the 10 character minimum counter bot happy.
