Ip address change permission denied

[Derek DiCamillo]

I installed a new router at the house that will not allow me to set the static IP address what I originally had. I can see proxmox in my list of connections on my router but get access denied. With that said I cant reach the gui.

I went to the command line and logged in as root as it looked like on the forums I needed to get to /etc/network/interfaces to update the ip address and I keep getting permission denied. Any ideas?

Please check your logs - /etc/network/interfaces should definitely be writeable as root - unless your / -filesystem is mounted read-only
(can happen if you have IO-errors on your disk, or if the system is not completely booted up and you're still too early in the boot sequence)

If you change the ip-address of your PVE-node make sure to also update the entry in '/etc/hosts' to point to your new IP - otherwise some important services will not start up

I hope this helps!
