Failed to download ns3 on virtual machine.
Failed to download ns3 on virtual machine.
Hello everyone. I need to set up ns3 on an Ubuntu VM for a lab at my university. I followed the instructions provided. After installing, I ran git clone https://gitlab.com/nsnam/ns-3-allinone.git and saw the same output as shown in the photo (sorry, I couldn't capture the screen on the VM). I wasn’t able to find any further guidance for this issue and am new to Ubuntu, so I’m struggling to resolve it. Do you have any suggestions?
