I installed Lubuntu as a guest OS in VirtualBox, and I tried installing the guest additions as I would in Windows, from "Devices->Insert Guest Additions CD Image... (Host+D)", and then running the autorun.sh
file.
This failed, however, with these errors:
The make utility was not found. If the following module compilation fails then
this could be the reason and you should try installing it.
The gcc utility was not found. If the following module compilation fails then
this could be the reason and you should try installing it.
Building the main Guest Additions module ...fail!
