I need to install an old version of Ubuntu (namely, 10.04) in a virtual machine using VirtualBox. Unfortunately it fails. My host operating system is Ubuntu Precise 32bit. I downloaded the 32bit image.
Just after selecting the mirror, the next screen asks for a http proxy (which I leave blank), then the "Downloading release files" window flashes briefly, finally it disappears and the screen stays blue with a grey band on the bottom.
I have tried to install the current Ubuntu version on the same virtual machine and it works perfectly. I tried VmWare Player, and it hangs the same way!!
I tried to google for it, but it seems nobody has experienced this?
