Indeed, there is a /run/network/ifstate.enp4s0 afther the error message is shown. > Can you try changing "ifup -a" in /etc/network/interfaces to "ifup --force > -a"? Changed line 142 of /etc/init.d/networking to `if ifup --force -a $exclusions $verbose && ifup_hotplug $exclusions $verbose`, but that didn't cause a difference. -- Best regards, Ivan
