Hi All,

Can someone please help me to resolve below issue?
I had moved server within same LAN, I'm able to ping from VM but from pve console, I'm trying to upgrade proxmox from 8.1.4 to 8.2

root@pve:~# ping -c4 google.com

Could you please check the following ?

In the "/etc/network/interfaces" the "gateway 192.168.1.142" seems unusual because most time GW's IP is the first or last of a given range.
Can you check against a (vitual) machine that have Internet access what is its gateway ?

In the "/etc/apt/sources.list" I don't see any line related to Proxmox. If you have no subscription you should see one line like the one below :
Code: 
deb http://download.proxmox.com/debian/pve bookworm pve-no-subscription

Hope it helps !

Thank you for the response. I changed the gateway, but still not working.

I have one more proxmox server, below is the config:
auto lo
iface lo inet loopback

iface enp0s31f6 inet manual

auto vmbr0
iface vmbr0 inet static
address 192.168.1.227/24
gateway 192.168.1.254
bridge-ports enp0s31f6
bridge-stp off
bridge-fd 0

iface wlp2s0 inet manual
