I had problem with install one app on Ubuntu and I had to switch back to Windows.
I hope Electrum will work, and we can soon see full version, but I do expect lot of bugs.
My laptop is windows so I don't need to install it in VirtualBox the reason why I use VirtualBox it's because you can only compile the Electrum Alpha version with Linux according to this https://github.com/spesmilo/electrum
Unless you know how to compile it on windows OS? It will help us if you can share it here.
