[Libguestfs] Libguestfs virt-builder network

Hi, I am trying to install a package inside a VM with virt-builder, and it seems I cannot connect to any repo, which means I probably have no network inside the guest. I installed it with: *sudo apt-get install libguestfs-tools* My OS-version: *Ubuntu 18.04* Command I used: *virt-builder ubuntu-16.04 --network --install git * I attached the complete output. I have also tried to install it from a tarball, 1.38.6, and the error persists. Should I somehow configure my network? Best regards, AG
