I used pre-up in /etc/network/interfaces. It's strange, I have two Ubuntu server, one a PC and another a VPS. This method works on my PC but not on my VPS.

This is the /etc/network/interfaces on my PC

Netplan does not support hook scripts:

https://netplan.io/faq#use-pre-up-post-up-etc-hook-scripts

The workaround is to use networkd-dispatcher. The above FAQ gives an example on how to do it.

The following is an example of using networkd-dispatcher to run existing ifup hooks via a script installed in /etc/networkd-dispatcher/routable.d/50-ifup-hooks:

#!/bin/sh

for d in up post-up; do
 hookdir=/etc/network/if-$d.d
 [ -e $hookdir ] && /bin/run-parts $hookdir
done
exit 0

Similarly, here is an example of an ifdown hook installed in /etc/networkd-dispatcher/off.d/50-ifdown-hooks:

#!/bin/sh

for d in down post-down; do
 hookdir=/etc/network/if-$d.d
 [ -e $hookdir ] && /bin/run-parts $hookdir
done
exit 0
