I cloned a Lubuntu 18.04 VM (running on ESXi). When I booted the cloned copy I edited the network connections (using the network menu in the lower right corner of the screen) and changed the IPV4 IP address so as not to clash with the original VM, then rebooted. Now I am unable to edit the network connections - nothing happens when I select "Edit Connection" from the networking menu. I've also noticed that the static IP address that I specified isn't being used - it seems to be getting a DHCP-assigned IP address. Any idea how I can get back in to fix this?
