I have a Windows 10 machine, with VirtualBox v5.0.16 r105871 installed. Over this, I am trying to host an Ubuntu 14.04.4 OS so that I can install and run the Robot Operating System (ROS). Here are some screenshots that show my setup:

The initial install of ROS desktop needs about 1.5GB, so I allocated 4GB of space for the Ubuntu OS. During installation, I run out of memory. This is the screenshot from Terminal:

ROS installation failed

So I go into the System Monitor to check. But everything looks fine - I have 4 GB and 3GB more to go:

System Monitor (only 1 GB used)

I followed the installation instructions at the ROS Indigo installation site to reach this point, and I'm stuck. I highly suspect that has nothing to do with ROS and can be solved if I can get the Ubuntu OS to recognize all 4GB of the disk, but I don't seem to be fiddling with the right controls.

Any help or guidance would be appreciated, thanks in advance!

  • As @Deltik mentions below, I think you're confusing memory/RAM with disk space here. To check for free space on Ubuntu, see this possible duplicate: [How to determine available free space on Ubuntu?](http://superuser.com/questions/94563/how-to-determine-available-free-space-on-ubuntu) (also, FWIW, 4GB is pretty small - I'd recommend choosing a much larger size like 40GB, but in a dynamically expanding volume, so it only takes up as much disk space is as written by the VM and not the entire 40GB). – Breakthrough Apr 06 '16 at 17:21

I think you've confused disk space and memory. You ran out of disk space, which you strongly suggested in your first screenshot. You did not run out of memory, as shown in your second screenshot.

df -hT will report your filesystem disk space usage. You can figure out which filesystem filled up (most likely /).

You can visualize what is taking up so much disk space with baobab (GNOME Disk Usage Analyzer), which may be built into Ubuntu 14.04 already.

If you can't delete anything else, you should have installed Ubuntu on a larger disk or partitioned the disk more effectively. There are ways to resize existing installations, but that's a much broader topic than in the scope of this answer.
