Hello. I am running the Kali Linux 2016.2 Release as a virutal machine in Virtualbox (installed from the Virtualbox image). After updating it with apt-get update && apt-get upgrade -y, the Kali VM got stuck in the middle of the upgrade. So I closed the VM and restarted it. Now when logging in using the GUI, I get a blank blue screen (no Kali logo). I can go to Applications (there are app titles but no icons), but if I load an app such as terminal or Firefox, I am automatically logged out. I also tried rebooting into recovery mode, where I get a terminal but there is no networking, so I cannot rerun the update. Is there another way to fix this?
