Bug#1118372: apt-daily-upgrade fails when eth0 is not present

Package: apt
Version: 3.0.3


I'm running Debian 13.1 Trixie in multiple containers. Last week I 
renamed the network devices in the Containers from eth0 to eth60. Since 
then can see the following lines in the "/var/log/syslog" of the containers:

2025-10-18T19:36:43+02:00 mojo-proxy systemd[1]: Starting 
apt-daily-upgrade.service - Daily apt upgrade and clean activities...
2025-10-18T19:37:13+02:00 mojo-proxy systemd-networkd-wait-online[295 
Timeout occurred while waiting for network connectivity.
2025-10-18T19:37:13+02:00 mojo-proxy apt-helper[293]: E: Sub-process 
/lib/systemd/systemd-networkd-wait-online returned an error code (1)
2025-10-18T19:37:14+02:00 mojo-proxy systemd[1]: 
apt-daily-upgrade.service: Deactivated successfully.
2025-10-18T19:37:14+02:00 mojo-proxy systemd[1]: Finished 
apt-daily-upgrade.service - Daily apt upgrade and clean activities.

This Timeout comes from the "apt" package: The 
"apt-daily-upgrade.service" calls "ExecStartPre=-/usr/lib/apt/apt-helper 
wait-online" which in turn calls 
"/usr/lib/systemd/systemd-networkd-wait-online". Which Times out.

The manual[1] of systemds "systemd-networkd-wait-online" clearly states 
that by default it only checks eth0. But it also has the parameter 
"--interface=" to handle the case when there is no eth0. I successfully 
used this Parameter in the "systemd-networkd-wait-online.service" which 
had the same problem as the "apt-daily-upgrade.service". Sadly this fix 
does not work in the "apt-daily-upgrade.service" case because it does 
not call "/usr/bin/systemd/systemd-networkd-wait-online" directly. And 
"apt-helper" has no factility in place to hand over the "--interface=" 
parameter to "systemd-networkd-wait-online".
