I'm trying to install guest additions but when I'm trying install ./VBoXLinuxAdditions.run I get "Failed to set up service vboxadd, please check the log file /var/log/VBoxGuestAdditions.log" and it is content:

vboxadd.sh: failed: modprobe vboxguest failed.

What should I do?

Usually this is caused when vboxguest can not be build on that machine, due to missing components (kernel-headers, compiler etc.). There should be another log file next to VBoxGuestAdditions.log which protocols the build progress. You will find the root cause there.

Additionally you can check out modinfo vboxguest and modprobe vboxguest, but I am pretty sure it is not available in the system because something like kernel headers are missing.
