Currently I have a small ssh network problem. I use an Ubuntu 20.4 Server Edition incl. autoinstall. I removed the network configuration from my user-data file because it should be better for the installation to select the adapters itself. Now I have the problem that after the first reboot my packer script cannot connect to ssh.
Only after entering the command dhclient -r and dhclient the packer script connected successfully with my Ubuntu installation.
