Almost a month after the previous version, VirtualBox has just released the new version 4.0.4 . For those who don’t know about VirtualBox please refer this post and come back. The new version of VirtualBox 4.0.4 is a bugfix release that improves the security and stability.
To install VirtualBox 4.0.4 in Ubuntu 11.04 Natty / 10.10 Maverick / 10.04 Lucid, open Terminal and type the following:
chmod +x vb_4.0.sh
This will install VirtualBox 4.0.4 in your Ubuntu. I haven’t tried it out yet, so if you have any problems related to installation please comment below.
