Hey everyone, I'm having some issues while trying to update my proxmox host, everytime I run sudo apt update from the cli (SSH) I get this error message.

Code:

TASK ERROR: command 'apt-get update' failed: exit code 100
It seems like the host does not have internet access since pinging any website or public IP gets an Destination host unreachable error. But it can ping local IP's and I can access it through SSH.
The weird thing is that every VM and container runing on Proxmox has internet access, and I've tried a lot of things from different post in this forum, and honestly I don't know what to try next.
It's important to note that the firewall is disabled at a datacenter level (and node level as well)
I'll leave the output of cat /etc/network/interfaces, cat /etc/apt/sources.list and a few screenshots:

cat /etc/network/interfaces
Code: 
# network interface settings; autogenerated
# Please do NOT modify this file directly, unless you know what
# you're doing.
#
# If you want to manage parts of the network configuration manually,
# please utilize the 'source' or 'source-directory' directives to do
# so.
# PVE will preserve these directives, but will NOT read its network
# configuration from sourced files, so do not attempt to move any of
# the PVE managed interfaces into external files!

I'll remain attentive to any question about my setup and/or issue.
Thanks everyone for your time and help.
Best regards
 
Your network config should look like this (so gateway to vmbr0 and not your NIC):
Code: 
auto lo
iface lo inet loopback

auto enp3s0
iface enp3s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 192.168.100.201/24
        gateway 192.168.100.1
        bridge-ports enp3s0
        bridge-stp off
        bridge-fd 0

Hi Dunuin,
I followed your post and with the network configuration Proxmox image given by @schanckbs the problem was solved for me today.

Kind regards,

Textfiles can be edited with a text editor like "nano". For example nano /etc/network/interfaces
