Installing over older version was not that hard this time.
First I created snapshots of each VM in my VirtualBox. Next create a restore point for Windows 7, just in case VB destroys stuff.
Then I downloaded and installed the new VirtualBox 4.1.4. It locked up. Went thru some stuff, showed a full taskbar but nothing. No exceptions or suspicious threads in Windows’s Proc Explorer. Install wouldn’t cancel either, had to kill it. Retried but it said there is another install going on. Did not see one in task list.
I rebooted Windows PC. Tried to start the existing Ubuntu VM, but it failed, one of the virtual network drivers is hosed. Shucks. Hmmm. Maybe VirtualBox will install again? This time I right clicked on the downloaded file and choose “Run As Admin”. It installed!
No 3D Unity interface. Guest Additions not updated. Clicked on device menu and install Guest Additions, nada!. I keep forgetting you have to install it manually for a Linux guest. For this I followed the VirtualBox user manual.
First do the steps in 184.108.40.206.1. I ran those using sudo. Second, follow steps in 220.127.116.11. Again using sudo. Shut down VM. In the VirtualBox gui, change the Ubuntu display to 3D. Start Ubuntu VM.
Success, I have the Unity interface again.
