Hi,
I actually try to install Cyberpanel (recently I need to tell that I install it on ESXi and all fine at 1st time). I try Ubuntu 20.04.. 18.04... Always have this :
What exactly does this have to do with Proxmox or VMware?
You obviously haven't configured something in the VM, probably the network at all, your bridge is not correct or you have incorrect DNS servers in the resolv.conf.
