Today I installed Virtualbox 1.5.4 from Ubuntu repository. It was installed successfully. But when I tried to run the Virtualbox, it showed an error message that asking me to install:
I tried to install a few times but synaptic seems didn’t like it, and aborted the installation. After a few minutes googling in the internet, I found the solution in the Linux Forums.
After I installed the correct kernel version of virtualbox and added my user login into “vboxusers” group, the Virtualbox works properly.
