I tried to install virtualbox for the first time on my ubuntu 16.04 machine following the instructions here. When tried to run from terminal with command
virtualbox it gave me the error below:
VirtualBox: Error -610 in supR3HardenedMainInitRuntime! VirtualBox: dlopen("/usr/lib/virtualbox/VBoxRT.so",) failed: <NULL> VirtualBox: Tip! It may help to reinstall VirtualBox.
and when tried to run by searching
virtualbox an icon appeared in sidebar and after some seconds disappeared.
I tried downloading the official
deb file form the virtualbox website and install with
sudo apt install ./virtual... but the same error happened.
I also completely removed virtualbox with
--purge option and its user and group every time I tried to reinstall.
The interesting part is that it was easy to install the
Virtualbox on an
ubuntu 16.04 hosted by another virtualbox on a
Any answer or comment would be appreciated.
Thanks to Charles the problem solved by changing the owner and group of
/usr/lib to root by the following commands:
sudo chown root:root /usr
sudo chown root:root /usr/lib
My problem was that I only changed the owner by
sudo chown root /usr.
