Hi,

After yesterday's TW update I found out that the VirtualBox GUI no longer starts. Instead, an error dialog pops up which says:

Effective UID is not root (euid=1000 egid=100 uid=1000 gid=100) (rc=-10)

Please try reinstalling VirtualBox.

chkstat seems to think that permissions are incorrect

# chkstat --warn /etc/permissions.easy Checking permissions and ownerships - using the permissions files /etc/permissions.easy /usr/lib/virtualbox/VirtualBox should be root:vboxusers 4750. (wrong permissions 0750) /usr/lib/virtualbox/VBoxHeadless should be root:vboxusers 4750. (wrong permissions 0750) /usr/lib/virtualbox/VBoxSDL should be root:vboxusers 4750. (wrong permissions 0750) /usr/lib/virtualbox/VBoxNetAdpCtl should be root:vboxusers 4750. (wrong permissions 0750) /usr/lib/virtualbox/VBoxNetDHCP should be root:vboxusers 4750. (wrong permissions 0750)

but when applying it refuses to do so

# chkstat --set /etc/permissions.easy Checking permissions and ownerships - using the permissions files /etc/permissions.easy setting /usr/lib/virtualbox/VirtualBox to root:vboxusers 4750. (wrong permissions 0750) /usr/lib/virtualbox/VirtualBox: will not give away s-bits on an insecure path setting /usr/lib/virtualbox/VBoxHeadless to root:vboxusers 4750.

(wrong permissions 0750) /usr/lib/virtualbox/VBoxNetDHCP: will not give away s-bits on an insecure path ERROR: not all operations were successful

I "fixed" this manually with

# chmod 4750 /usr/lib/virtualbox/VirtualBox /usr/lib/virtualbox/VBoxHeadless /usr/lib/virtualbox/VBoxSDL /usr/lib/virtualbox/VBoxNetAdpCtl /usr/lib/virtualbox/VBoxNetDHCP

but this will probably reappear when I next update so I'm interested in a more permanent solution.

What's the proper solution to this issue?

This probably means there is either a symlink or a world writeable directory involved.

Can you check:

ls -la /usr/lib/virtualbox ls -la /usr/lib | grep virtualbox ls -la /usr

Thanks for the hint. Those directories were properly set up. However, '/' was owned by 1000:100 , for which I have no explanation. Once I fixed the permissions chkstat was happy again.

Thanks,

Robert
