I've been trying to use OpenVAS from my kali live USB. Its a fresh USB (64GB) I formatted it and added kali linux to it using universal USB installer. I booted into kali and began to use it. To use OpenVAS I needed to apt-get update and apt-get dist-upgrade. While going through these I get an error saying that Disk space is full. When I check the space it says that i only have 2GB total. When I open the drive on windows it shows that i still have like 60+ GBS available. Please Help!
