Hello,
I have had a Proxmox VE nodes running for months now without issues. Today I decided to update the packages (no-subscription repo) through the web interface and restart it. However, after doing so my node no longer connects to the internet. I did a lot of searching, and this seems to be a common issue when the /etc/network/interfaces file is misconfigured, but mine seems to be setup correctly.
Here is the output from ip a and cat /etc/network/interfaces:

Contents of /etc/resolv.conf:
search test
nameserver 1.1.1.1
I tried adding auto enp0s31f6, setting enp0s31f6 static, setting both interfaces dhcp, setting enp0s31f6 static and dhcp and removing vmbr0, and connecting a USB Ethernet adapter and setting it as static. No matter what I try it will not connect to the local or outside network.
Also, the ifup and ifreload commands keep returning 'permission denied' even though I am root so I am rebooting the server every time I change something.
SOLVED: Most likely node got restarted while updating and some things got corrupt. We tried many things but running dpkg --configure -a after apt upgrade seemed to fix it.
