I'm running Ubuntu 12.04.3 . I have a problem with the version from the default repositories (can't build modules for current kernel, see: http://ubuntuforums.org/showthread.php?t=2177440). After some Googling, I discovered that the problem may be fixed by installing a newer version of Virtualbox. I want to install this PPA: https://launchpad.net/~debfx/+archive/virtualbox
However, is this PPA safe? Does it contain malware or badly compiled software, etc. ? Can I safely add this PPA?
Thank you in advance.
