Dear Proxmox user list,

My network and internet connections work fine but I'm getting a "State: degraded" from systemctl status,
since an apt-get dist-upgrade yesterday. That Proxmox (6.1-7) update did rewrite my /etc/network/interface
configuration file, but it looked harmless:

#cat /etc/network/interfaces
auto lo
iface lo inet loopback

iface enp4s0 inet manual

auto vmbr0
iface vmbr0 inet static
        address 172.17.2.6/24
        gateway 172.17.2.1
        bridge-ports enp4s0
        bridge-stp off
        bridge-fd 0
        hwaddress 52:54:56:17:02:06

However, today after a reboot, I'm getting the following errors:

#systemctl status networking.service
● networking.service - Network initialization

Can anyone see what I have done wrong? Has someone experienced the same issue?
Is there anything I should check or correct? (I have IPv6 disabled in sysctl because I don't use it.)

kind regards, Arjen
