"In post #9 and in post #11 evo requested that you post what the konsole/terminal retured."
05-25-15, 01:18 PM also contained the output of both the terminal and log, shall i continue to repeat the same error redundantly or what? Admittedly, i missed this second page to this thread until now and for some reason was not informed via email it was even hear, by manually coming here and looking closer did i even find this.
EDIT (To clarify/simplify):
[FAIL] Failed, trying without DKMS ... failed!
[....] Recompiling VirtualBox kernel modules:
[FAIL] Look at /var/log/vbox-install.log to find out what went wrong ... failed!
THE LOG:
Makefile:172: *** Error: unable to find the sources of your current Linux kernel.
Specify KERN_DIR=<directory> and run Make again.
sudo apt-get install dkms don't work in ither terminal or package managment.
"If you didn't choose a mirror for your distribution to pull pkg's, security updates and etc. that's probably what is contributing to things not installing" -Yes, it was an offline install. I had that problem and thought i had fixed it within the source lists as shared. It must not have been, how to be sure?
"Yum is the command line utility for installing pkg's and software on Red Hat based distributions. Kali Linux is based on Debian which does not use yum. " -I said that earlier but it was ignored it seems, when i used a yum command as a sudo command instead it was experimental, as stated in the original post; sometimes that substitution works. But it is a hit and miss thing. One poster tried to say yum would simply work.
Ok

Not touching that subject.
If i missed something else feel free to let me know otherwise those who will not read it as it is will not be helpful and can not be expected nor asked to. Throwout this thread, as per error received, one at a time, in the order received it is posted accordingly.
New plan (in the order listed - as wrote) logged in as Root:
sudo apt-get install build essentials
sudo apt-get install linux-headers-$(uname -r)
sudo apt-get install dkms
sudo apt-get install virtualbox-4.
sudo apt-get update
The result:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package build
E: Unable to locate package essentials
Searched the Add/Remove Software inside Aplications > System Tool's
Found build-essential-11.5 (23-bit)
Question: Am i missing the "-"'s?
Retryed with:
sudo apt-get install build-essentials
Resulted in:
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package build-essentials
I think at this point we, (including myself,) should re-read this thread just to clarify/be on the same line of idea and ensure were all strait with this. Thanks to all who are trying, its appreciated.

Apology's about the confusion.
