Hi Steffen,
That is weird; this should work even for pure debian.
However, reading my message, I saw that some parts of my scripts are
useless. Maybe you can try the following instead (just replacing $NIC1 by
$iface which is not used) :
```
#! /bin/bash
iface=`ip -o -f inet addr show |awk '$2 !~ "lo|docker" {print $2;exit;}'`
mac=`ip -o -f link addr |awk -v iface=$iface '{ if ( $2 == iface":" )
{print;} }' |cut -d"/" -f2|awk '{print $2}'`
fields="ID_NET_NAME_FROM_DATABASE ID_NET_NAME_ONBOARD ID_NET_NAME_SLOT
ID_NET_NAME_PATH"
for field in $fields; do
name=$(udevadm info /sys/class/net/$iface | sed -rn "s/^E:
$field=(.+)/\1/p")
if [[ $name ]]; then
newnicname=$name
break
fi
done
fcopy /etc/netplan/01-netcfg.yaml
fcopy /etc/cron.d/dhclient
sed -ri "s|inet_to_replace|$newnicname|" $target/etc/netplan/01-netcfg.yaml
sed -ri "s|inet_to_replace|$newnicname|" $target/etc/cron.d/dhclient
sed -ri "s|inet_to_replace|$newnicname|" $target/etc/network/interfaces
sed -ri "s|mac_to_replace|$mac|" $target/etc/netplan/01-netcfg.yaml
```
What would be interesting would be to get your logs, particularly your
"variables.log" (for example, to check $NIC1) and "error.log".
Moreover, if you can also supply your network configuration files
(/etc/network/interfaces and so on...), it would be useful.
Best regards,
Rémy.
