I don't know what you searched for.

ifup has --all as one of its possible options. The man page uses
IFACE as a placeholder for the interface name, ie

  ifup -a|IFACE...

would be specified as

  ifup -a

or

  ifup --all

or

  ifup wlan0

or

  ifup wlan0 eth1

etc. I don't use ifup much, but typically the d-i would install
something like

  allow-hotplug enpXsY
  iface enpXsY inet dhcp

into /e/n/i.

However, the man page implies that you could write just

  auto

and I wonder what ifup command would be generated from that.

What does your /etc/network/interfaces (and subdirectories) contain?

A workaround for your problem might be to set IFACE appropriately
in /etc/default/macchanger.

Cheers,
David.
