So I was able to do this:
./VBoxLinuxAdditions.run I got the warning
could not find the X.org or xfree86 window system, skipping
When I do
lsmod | grep guest I get
vboxguest /*numbers*/ 3 vboxsf, vboxvideo /numbers/ is actual number code that I can't remember.
When I do VBoxService --version I get 5.1.26, which is the version for my VM VirtualBox.
I have spent hours and hours trying to get this work, I do not want my time to be spent in vain. Any help?
So after installing gcc
sudo apt-get install gcc I rebooted
reboot. But I still was not able to CRT + SHIFT + V, here is
/var/logs/vboxadd-install.log after installing gcc and rebooting.
Above the line "make1: gcc: Command not found was just the same stuff from the first image, and under "Creating user for the guest additions" was
en0ps3: reset adapter. and the same line "creating udev rule for the Guest Additions kernel module.
