I'm doing a Cybrary course that uses this VM from PentesterLab.com. I've downloaded the .ISO and launched it in VirtualBox v5.2.4. The VM boots up into Debian and works fine, but I can't seem to install a GUI.
I've tried Gnome, because that seems to be the most popular one, but none of the following commands work:
sudo apt-get install gnome sudo apt-get install gdm sudo apt-get install gdm3 sudo apt-get install gnome-desktop-environment
Trying them with the
-m switches doesn't help. All of them say "Unable to locate package" except for
gdm3, which actually tries to install but lists a bunch of dependencies and says "but it is not installable" for each one.
When I do
sudo apt-get update it runs but with some "Failed to fetch" errors.
The VM is bridged and has network connectivity; it has its own IP address on my network and can ping and be pinged from other computers, as well as ping Internet sites. The VM has base memory of 1024MB and an 8GB virtual hard drive. It's running 32-bit Debian 2.6.32-5-686.
I'm not sure if the problem is related to Linux, the VM environment, or me not knowing what I'm doing.
